Abstract
The heat stability of arylene sulfide resins, such as poly(p-phenylene sulfide) resin, is improved by the addition of cure retarders comprising certain organotin compounds such as the dialkyltin dicarboxylates. The resin compositions of the invention are particularly applicable for reducing gel formation during melt extrusion.
