ABSTRACT:
A polymer composition having improved thermal stability at high temperatures. The composition comprises a poly(phenylene sulfide) base resin and a thermal stabilizer selected from the group consisting of polyethersulfone and polyamide-imide, the thermal stabilizer being present in the composition in an amount sufficient to improve the thermal stability of the composition at a temperature of at least 150.degree. C. A method of improving the thermal stability of a poly(phenylene sulfide) resin and articles produced therefrom at high temperatures and an article having improved thermal stability at high temperatures are also provided.
