摘要
利用受体催化缩聚的方法，以缩合度为 n = 1-20 的各种低聚物为基础，获得了含有 >C=CCl2 基团的嵌段聚醚酮，其特点是具有较高的热性能和机械性能、定量收率和较高的降低粘度值。所得聚酯的结构已得到确认。研究了双键部位聚酯结构化的动力学，这取决于温度和停留时间。
Synthesis and properties of unsaturated block copolyether ketones
Block-copolyether ketones containing >C=CCl2 groups, characterized by high thermal and mechanical properties, with quantitative yield and high values of reduced viscosity, were obtained based on various oligomers with condensation degrees of n = 1-20 using the method of acceptor-catalytic polycondensation. The structure of the resulting polyesters was confirmed. The kinetics of polyester structuring at the site of the double bond depending on temperature and dwelling time was studied.
