1. A process for optimizing the crystallization behaviour of polyester moulding compositions or the crystallinity of products to be produced from the polyester moulding compositions, the process comprising producing a polyester moulding composition comprising polybutylene terephthalate (PBT) and polyethylene terephthalate (PET) at a PBT:PET ratio by weight of 5:1 to 0.2:1, wherein the polyethylene terephthalate has an alkali metal content of 1 to 10,000 ppm. |
