ABSTRACT:
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-polymerization 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.degree. C. to lower the curing temperature of the coating composition. The compositions are particularly suited for application in which curing temperatures of 350.degree. C. or lower are desired.
