ABSTRACT:
A two-step process to make a poly(arylene sulfide sulfone) polymer exhibiting improved high temperature properties is described. In the first step a prepolymer characterized as dihalo-terminated polyethersulfone oligomers is prepared by reacting an aromatic diphenol with an excess of a dihalo aromatic sulfone. In the second step the excess dihalo aromatic sulfone and the oligomers are copolymerized in the presence of a sulfur source to form a poly(arylene sulfide sulfone)polymer. An alkali metal carboxylate is present in the second step. The polymers exhibit improved softening temperature and glass transition temperature and are useful in high temperature applications.
