ABSTRACT:
The heat stability of arylene sulfide resins, such as poly(p-phenylene sulfide) resin, is improved by the addition of cure retarders comprising phenolic amide or ester-based antioxidants. The resin compositions of the invention are particularly applicable for reducing gel formation during melt extrusion.
