MELT STABILIZATION OF POLY(ARYLENE SULFIDE SULFONE)S

摘要

Improved poly(arylene sulfide sulfone)s are prepared by contacting these polymers with a zinc source, optionally first with an alkali metal base, for a period of time sufficient to incorporate enough zinc cations to improve the melt stability of the polymers. The polymer can be subsequently cured to increase molecular weight. The melt stable poly(arylene sulfide sulfone)s can be processed in conventional commercial applications to provide fibers, film, moldings and other articles of manufacture.
