Poly(arylene sulfide) coating compositions.

摘要

A poly(arylene sulfide) coating composition, method of preparing the composition, and method of coating are disclosed. The composition comprises a finely-divided poly(arylene sulfide) having from about 75 to about 99 mole percent para-polymerized aromatic units and from about 1 to about 25 mole percent ortho- or meta- polymerized aromatic units and, optionally, from about 0.1 to about 2 mole percent trifunctionally-polymerized aromatic units. The coating resin can be prepared in a polymerization reaction medium containing a molar excess of base, with respect to sulfur present, and can be washed with water at at least about 100 DEG C to lower the curing temperature of the coating composition. The compositions are particularly suited for application in which curing temperatures of 350 DEG C or lower are desired.
