And the article contained the following:

Bismaleimide (BMI) resins have poor toughness due to their high crosslink d., which limits their wide development and application. In this study, the amino-terminated poly(phthalazinone ether nitrile sulfone) (PPENS-DA) resin was designed and the curing agent of 3,3′-diallyl-4,4′-biphenol (DABP) was synthesized to toughen N,N’-(4,4′-diphenylmethane) bismaleimide (BDM) resin. The impact strength, flexural strength and fracture surface structures of the DABP/BDM and PPENS-DA/DABP/BDM blends were studied. The results showed that the notched impact strength of the blends with 10-phr PPENS-DA is 4.98 kJ/m2, which was 36% higher than that of pristine BDM/DABP blend and 200% higher than that of the 2,2′-diallyl bisphenol A (DABPA) modified BMI resin system. The glass transition temperature (Tg) has been improved from 247 to 269°C for the blend system as evidenced by DMA. Rheol. behavior anal. indicated that the blend system has a broad processing window (90-175°C) with low viscosity of less than 1 Pa·s and low curing activation energy of 67.2 kJ/mol. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Synthetic Route of 80-07-9

Igder, Aghil; Pye, Scott; Mohammed Al-Antaki, Ahmed Hussein; Keshavarz, Alireza; Raston, Colin L.; Nosrati, Ata published an article in 2020, the title of the article was Vortex fluidic mediated synthesis of polysulfone.Application In Synthesis of 4,4′-Sulfonylbis(chlorobenzene) And the article contains the following content:

Polysulfone (PSF) was prepared under high shear in a vortex fluidic device (VFD) operating in confined mode, and its properties compared with that prepared using batch processing. This involved reacting the pre-prepared disodium salt of bisphenol A (BPA) with a 4,4′-dihalodiphenylsulfone under anhydrous conditions. SEM (SEM) established that in the thin film microfluidic platform, the PSF particles are sheet-like, for short reaction times, and fibrous for long reaction times, in contrast to spherical like particles for the polymer prepared using the conventional batch synthesis. The operating parameters of the VFD (rotational speed of the glass tube, its tilt angle and temperature) were systematically varied for establishing their effect on the mol. weight (Mw), glass transition temperature (Tg) and decomposition temperature, featuring gel permeation chromatog. (GPC), differential scanning calorimetry (DSC) and thermal gravimetric anal. (TGA) resp. The optimal VFD prepared PSF was obtained at 6000 rpm rotational speed, 45° tilt angle and 160°C, for 1 h of processing with Mw ∼10 000 g mol-1, Tg ∼158°C and decomposition temperature ∼530°C, which is comparable to the conventionally prepared PSF.

And the article contained the following:

In this study, a series of fluorinated polyethersulfone (PES-6AF) copolymers with intrinsic low-dielec.-constants are prepared by the introduction of fluorine-containing group, which are derived from the polycondensation reaction of 4,4′-dichlorophenyl sulfone (DCS), bisphenol S (BPS) and six fluorine hexafluorobisphenolA (6AF) compounds by nucleophilic aromatic substitution. Different proportions of PES-6AF copolymers show high glass transition temperatures (Tg) ranging from 206°C to 230°C, and the thermal decomposition temperatures of PES-6AF copolymers are up to 500°C under N2 atmospheres. The PES-6AF copolymers display outstanding tensile strength (62-69 MPa). Added different proportions of 6AF into the PES-6AF copolymers could improve dielec. property and decrease dielec. constant (k) from 3.6 to 2.5 at 1 kHz. In addition, the dielec. properties were found to be relatively stable until the Tg, it is because that the 6AF units were existed in the mol. backbone. Furthermore, the PES-6AF copolymers were soluble in many common solvents and could be made the molten films using DMF as solvent. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).HPLC of Formula: 80-07-9

And the article contained the following:

Long-chain-branched poly(aryl ether sulfone)-poly(tetrahydrofuran) multiblock copolymers (PES-BPTHF) composed of hard linear and soft branching segments were synthesized from bromo-terminated poly(tetrahydrofuran) and hydroxy-terminated poly(aryl ether sulfone). A study on the effect of concentration on polymerization behavior revealed that soluble powder was obtained at the optimized reaction concentration of 7 wt%. Gelation and intramol. cyclization were observed at high and low concentrations, resp. The microphase-separated morphol. of PES-BPTHF was confirmed by at. force microscopy, small-angle X-ray scattering, and dynamic mech. anal. measurements. Fewer entangled poly(tetrahydrofuran) segments were detected in PES-BPTHF than in PES-PTHF by SAXS, DMA and tensile measurements. Rheol. measurements suggested high chain entanglement of PES-BPTHF in its melt phase. It is interesting to note that the polymer chains in the soft domains become less entangled and more reminiscent of hyperbranched architectures, whereas the overall chain entanglements are increased due to the long-chain-branched structure. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Safety of 4,4′-Sulfonylbis(chlorobenzene)

On May 31, 2022, Li, Jianying; Huang, Bin; Tang, Huali; Cai, Mingzhong published an article.Name: 4,4′-Sulfonylbis(chlorobenzene) The title of the article was Synthesis of novel aromatic polyamides containing both sulfone linkages and cardo groups by a recyclable palladium-catalyzed carbonylation and condensation polymerization. And the article contained the following:

A series of novel aromatic polyamides containing both sulfone linkages and cardo groups were synthesized via a heterogeneous palladium-catalyzed carbonylation and condensation reaction of aromatic diiodides bearing ether sulfone linkages, carbon monoxide, and aromatic diamines with cardo groups. Polycondensation reaction proceeded smoothly under 1 atm of CO at 120°C in N,N-dimethylacetamide (DMAc) by using a bidentate phosphine ligand-modified magnetic nanoparticles-anchored palladium complex [2P-Fe3O4/SiO2-PdCl2] as a recyclable catalyst with 1,8-diazabicycle[5,4,0]-7-undecene (DBU) as a base, furnishing cardo poly(ether sulfone amide)s with inherent viscosities between 0.70 and 0.77 dL/g. The resulting polyamides could be readily dissolved in polar aprotic organic solvents and even dissolved in less polar pyridine and THF at room temperature and could be easily converted into flexible, transparent, and tough films via casting from their solutions in DMAc. These polymers exhibited excellent thermal stability with the glass transition temperatures between 241 and 283°C and the temperatures at 5% weight loss ranging from 438 to 475°C in an atm. of nitrogen. The polyamide films displayed good mech. behavior with tensile strengths of 78.8-84.4 MPa, tensile moduli of 2.08-2.57 GPa, and elongations at breakage of 10.2-12.5%, and optically high transparency with cut-off wavelengths in the range of 338-368 nm.

On April 30, 2020, Liu, Limin; Li, Jianying; Yan, Tao; Cai, Mingzhong published an article.Electric Literature of 80-07-9 The title of the article was Novel preparation of poly(arylene ether sulfone amide)s via supported palladium-catalyzed carbonylative polymerization. And the article contained the following:

Two new aromatic diiodides with ether-sulfone linkages were synthesized via a 1-step procedure. Poly(arylene ether sulfone amide)s were synthesized by a supported Pd-catalyzed polycondensation of aromatic diiodides having ether-sulfone linkages, aromatic diamines, and CO. Polycondensation reactions were conducted in N,N-dimethylacetamide using a magnetic nanoparticles-bound Pd(II) complex [Fe3O4@SiO2-2P-PdCl2] as the catalyst and 1,8-diazabicycle[5,4,0]-7-undecene as the base at 120°, yielding poly(arylene ether sulfone amide)s having inherent viscosities of 0.43-0.77 dL/g. The resulting polymers were soluble in polar aprotic solvents and showed glass transition temperatures in the 204-265° range, with 10% weight losses occurring at temperatures >456° in N. Most of the polymers afforded transparent and tough films by solution-casting with tensile strengths of 71.8-82.2 MPa, Young’s moduli of 1.77-2.35 GPa, and elongations at break of 9.3-13.4%. More importantly, this supported Pd catalyst can facilely be separated from the product by simply using an external magnetic field and reused at least 7 times with almost consistent activity. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Electric Literature of 80-07-9
