Abstract

Phenylene sulfide oligomers are produced by heating at least one aromatic sulfide in an oxygen-containing gaseous atmosphere at an elevated temperature and for a period of time sufficient to form the oligomers. The oligomers can be cured by heating in an oxygen-containing atmosphere while the oligomers are being produced or in a subsequent step after production to yield cured oligomers having utility as coatings, films, and the like.
