| Zusammenfassung: | Composition comprises polybutylene terephthalate and polyethylene terephthalate, where the weight ratio of polybutylene terephthalate and polyethylene terephthalate is 5:1-0.2:1 and the polyethylene terephthalate has a sodium and/or potassium content of 1-10000 ppm. Independent claims are included for: (1) optimizing the crystallization behavior of polyester molded materials or the crystallinity of the obtained products using the composition; and (2) products obtainable by injection molding of the composition. |
