Impact-resistant thermoplastic polyester compositions of low melt viscosity, process for their preparation, and their use for the production of mouldings |
摘要 |
Polyalkylene terephthalates which contain small quantities of aliphatic polycarbonate show improved fracture behavior, without a significant adverse effect on the strength and the flowability in the melt. Moreover, the compositions show improved behavior in hot-air ageing.
