Abstract

Изобретение относится к способу получения сложного полиэфира с улучшенными свойствами плавления и кристаллизации, включающий в себя следующие этапы: a) приготовление расплава сложного форполиэфира со средним молекулярным весом (Mn) 2000-16000 г/моль, b) отверждение и формирование частиц из сложного форполиэфира, c) термическую обработку частиц сложного форполиэфира в твёрдой фазе в присутствии катализатора переэтерификации, сопровождающуюся ростом молекулярного веса (дельта Mn) более чем на 2000 г/моль, причём перед этапом с) частицы сложного форполиэфира содержат концевые карбоксильные группы (X) в количестве 0,25-0,6 и во время термической обработки на этапе с) доля реакции этерификации (Е) в реакциях поликонденсации (Е+Т) составляет 0,5-1.
