A novel fluoropolymer having triazine rings and thermo-crosslinkable benzocyclobutene units is prepared by a facile phase transfer catalyzed interfacial polycondensation reaction between a diphenol and a dichloro-s-triazine. This is the first example of thermo-crosslinkable fluoropolymer containing triazine units. The polymer shows a high mol. weight (Mn) of more than 70 000, good solubility and film-forming ability, as well as high storage stability. When treated at a high temperature (>200 °C), the polymer easily converts to a crosslinked network, showing a low dielec. constant (Dk) of 2.58 at a range of frequencies from 0.1 to 30.0 MHz. Moreover, the crosslinked network exhibits a dielec. strength of 157.7 kV cm-1, which is comparable with that of a widely used resin poly(2,6-dimethyl-1,4-phenylene ether). D-E loop tests indicate that the cured polymer possesses linear dielec. properties. The cured polymer also exhibits high hydrophobicity, which endows the polymer with a low water uptake of 0.11% after immersing it in water at room temperature for 72 h. Moreover, the crosslinked network exhibits high thermo-stability with a glass transition temperature of 264 °C and a 5 wt% loss temperature of 426 °C, as well as good mech. properties with an average hardness of 0.48 GPa and an average Young’s modulus of 11.92 GPa. Hence, this new fluoropolymer is suitable as a new dielec. matrix resin for the production of printed circuit boards used in the microelectronic industry. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Application of 122-18-9).
N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Application of 122-18-9
