PROCESS FOR THE PREPARATION OF POLY(ARYLENE SULFIDE) WITH LOW METAL CONTAMINATION AND POLYMER PRODUCED

摘要

A process for preparing poly(arylene sulfide) with reduced metal contamination is produced by contacting a dihaloaromatic compound, a sulfur source, a polar organic compound, and an alkali metal carboxylate in a reaction vessel wherein at least the liquid contacting parts of the vessel are constructed of titanium. In another aspect of the invention a polymer produced by the above described process is provided.
