ABSTRACT:
Polymerizable molding compositions having excellent pigmentability and dimensional stability comprise:
A. polymerizable polyester component and
B. an additive component comprising discrete particles of less than about 50 microns diameter of a cross-linked acrylate polymer having a glass transition temperature of below about 75.degree. Celsius and which is chemically inert with respect to the polyester component and is swellable but insoluble therein. The additive component comprises the lightly cross-linked reaction product of at least one monofunctional acrylate monomer and at least one polyfunctional acrylate monomer.
