Low profile polyester molding composition

摘要

Dimensionally stable, pigmentable polyester molding compositions comprise: (A) a polymerizable polyester component; and (B) an additive component comprising discrete particles of less than about 50 microns diameter of a lightly cross-linked styrene terpolymer having a glass transition temperature of below about 100 DEG Celsius and which is chemically inert with respect to the polyester component and is swellable but insoluble therein. The additive component is the reaction product of styrene, an unsaturated monofunctional comonomer and a polyfunctional monomer such as divinyl benzene.
