Thermoplastic blend compositions containing polyester resins and an organosulfate salt

U.S. Patent Number: 5648411

Abstract: Thermoplastic compositions exhibiting enhanced melt stability are provided. The compositions contain a blend of resins and an organosulfate salt. The resin blends are preferably selected from (a) a blend of a polyester resin, such as polybutylene terephthalate, and aromatic polycarbonate resin, and (b) a blend of a low molecular weight polyester resin and a high molecular weight polyester resin. The compositions exhibit enhanced retentions of cystallinity and related properties, during melt processing.
