Poly(arylene sulfide)/poly(arylene sulfide sulfone) block copolymers and preparation thereof

摘要

A process is provided for preparing poly(arylene sulfide) /poly(arylene sulfide sulfone) block copolymer comprising: contacting poly(arylene sulfide) prepolymer, a dihaloaromatic sulfone, a sulfur source, and a polar organic compound under polymerization conditions, wherein said prepolymer is prepared by contacting a dihaloaromatic compound, a phenolic compound, a polar organic compound, and a sulfur source under polymerization conditions.
