Ladelta, Viko; Zapsas, George; Abou-hamad, Edy; Gnanou, Yves; Hadjichristidis, Nikos published an article in 2019, the title of the article was Tetracrystalline Tetrablock Quarterpolymers: Four Different Crystallites under the Same Roof.Recommanded Product: trimethyloxosulphonium chloride And the article contains the following content:
Multicrystalline block polymers having three or more crystalline segments are essential materials for the advancement of physics in the field of crystallinity. The challenging synthesis of multicrystalline polymers has resulted in only a limited number of tricryst. terpolymers having been reported to date. We report, for the first time, the synthesis of polyethylene-b-poly(ethylene oxide)-b-poly(ε-caprolactone)-b-poly(L-lactide) (PE-b-PEO-b-PCL-b-PLLA), a tetracryst. tetrablock quarterpolymer, by combining polyhomologation, ring-opening polymerization, and an organic/metal “catalyst switch” strategy. 1H NMR spectroscopy and gel-permeation chromatog. confirmed the formation of the tetrablock quarterpolymer, while differential scanning calorimetry, X-ray diffraction, and wide-line separation solid-state NMR spectroscopy revealed the existence of four different crystalline domains. The experimental process involved the reaction of trimethyloxosulphonium chloride(cas: 5034-06-0).Recommanded Product: trimethyloxosulphonium chloride
