Thermoplastic block copolyesters, a process for the preparation thereof and their use for the production of mouldings |
| 摘要 |
Block copolyesters based on polyalkylene terephthalates which contain polydiene blocks show an extremely low deformation even when they are processed into thin articles. They still have a crystallinity which is decreased by less than the ratio corresponding to the polydiene portion.
