Self-extinguishing, film-forming, linear polyarylates

Self-extinguishing, film-forming, linear polyarylates

Self-extinguishing, film-forming, linear polyarylates are prepared by interfacial polycondensation of chlorobisphenols, at least one of which contains a carbon atom, between two aryl rings, which is connected by a double bond to a -CCl2 group, or a mixture of these chlorobisphenols with bis (hydroxy...

description Self-extinguishing, film-forming, linear polyarylates are prepared by interfacial polycondensation of chlorobisphenols, at least one of which contains a carbon atom, between two aryl rings, which is connected by a double bond to a -CCl2 group, or a mixture of these chlorobisphenols with bis (hydroxyaryl) alkanes, and dicarboxylic acid chlorides or mixtures thereof in the presence of quaternary salts of an ammonium or phosphonium base. The polyarylates have very good film-forming properties and a high thermostability up to 360 DEG C.
