Abstract
Thermoplastic polyester composites are prepared from compositions comprising a filler, at least one macrocyclic poly(alkylene dicarboxylate) oligomer and a polymerization catalyst therefor. The use of polyester oligomer mixtures is preferred, and they may be present in liquid or solid form. The polyester composites prepared therefrom are characterized by excellent properties including solvent resistance.
