Abstract:
A thermoplastic resin molding composition, which comprises;a thermoplastic resin; andan additive consisting of a thermoplastic polymer, and an aqueous latex of a fluoropolymerwherein said latex is highly dispersed and encapsulated within said thermoplastic polymer as a result of providing an organic solution of the thermoplastic polymer, admixing the aqueous latex of the fluoropolymer with the organic solution of thermoplastic polymer and steam precipitating the admixture whereby the fluoropolymer is encapsulated by the thermoplastic polymer to form particles having a core and a shell, the fluoropolymer in solid form is the core and the thermoplastic resin is the shell resulting in the diminution of the occurrence of black specks and crack propagation in articles molded therefromwherein the thermoplastic resin is a polyalkylene terephthalate resin.
