ARYLENE SULFIDE POLYMERS

摘要

Arylene sulfide polymers having a high extrusion rate, e.g. at least about 100g/10 min. are prepared by a process comprising: a) dehydrating an aqueous admixture of a suitable sulfur source and a cyclic organic amide; b) admixing a dihalo-substituted aromatic compound with the dehydrated mixture to form a polymerization mixture wherein the molar ratio of sulfur source to the cyclic organic amide is about 0.39:1 to about 0.6:1; c) subjecting the polymerization mixture to reaction conditions sufficient to produce the arylene sulfide polymer; and d) recovering the arylene sulfide polymer.
