Polyphenylene sulfide (PPS) is an engineering plastic with excellent thermal, mechanical, and electrical properties, and has received considerable attention during the last few years. There are numerous reports on the crystallization behavior and physical properties of PPS (1-7). This polymer can be processed by conventional melt-processing techniques such as injection molding, compression molding, etc., and also by powder metallurgical technique. However, there are few reports on the powder processing of PPS (8, 9).
