ABSTRACT:
This invention concerns thermoplastic polyester molding compositions containing iron oxides, particularly Fe.sub.2 O.sub.3 which compositions exhibit markedly reduced heat up times and are especially useful in molding operations such as blow molding of beverage bottles. The polyester polymer may have incorporated therein by copolymerization certain anthraquinone dyes having functional groups which condense during polymerization into the polyester chain. The dye moieties are thermally stable at the polymer processing temperatures and are colorfast and non-extractable from the polymer.
