Poly(arylene thioether) copolymers and process for production thereof.

摘要

A novel class of poly(arylene) thioether) copolymers which are not only thermoplastic but thermosetting in nature. The copolymer may be prepared by copolymerizing a combination of dihalogenobenzonitrile, dihalogenobenzophenone and thioetherifying agent in an organic solvent. The copolymers are highly resistant to heat and solvents and exhibit excellent mechanical properties at raised temperatures.
