Abstract
The heat stability of arylene sulfide resins, such as poly(p-phenylene sulfide) resin, is improved by the addition of cure retarders comprising Group IIA or Group IIB metal salts of fatty acids. The resin compositions of the invention are particularly applicable for reducing gel formation during melt extrusion.
