ABSTRACT:
A process for efficiently manufacturing polyarylene sulfide copolymer in which polymers are well dispersed and which copolymer exhibiting superior mechanical properties. The process comprises reacting a polyarylene sulfide resin (A) and an amination agent (B) in a non-protonic organic solvent (C), and copolymerizing the resulting amino polyarylene sulfide resin (A') and a reactive elastomer (D) in a non-protonic organic solvent (C'), thereby obtaining a polyarylene sulfide resin (A") with the elastomer dispersed in the resin matrix.
