    Abstract: Thermoplastic polyester compositions comprising at least two groups of polybutylene terephthalate with substantially different intrinsic viscosity values and conventional additives for molding having an improved thermal flow capability under molding conditions expressed in such indices as heat flow (m cal/sec), enthalphy change .DELTA.Hm(Joule/gr) at the solidification of fused polymer, crystalline fraction (Xc), and the time of growth to (sec) of the primary nuclei of embryonic crystalline. The polymer compositions of the present invention result in a larger size of crystalline than the case of independent, single polymer and this enables to carry out injection moulding at about 20 degrees lower cylinder temperature than usual molding practice without sacrificing mechanical and thermal properties of the product.
