| 摘 要： | 研究了偏氟乙烯的聚合条件与其聚合物的头-头链含量的关系。实验表明聚合物的头-头链的含量与聚合温度有关,而与引发剂的种类无关。因而,可以在较低的聚合温度下聚合制得带有低的头-头结构(约3％)的聚偏氟乙烯。将聚合物链的A结构含量对其熔点作图,得一直线,可表示为方程式A=24.8+0.362T_m(％)。

| Abstract: | The relation between polymerization conditions of vinylidene fluoride and content of head-to-tail chain in the polymer have been studied. It shows that the content of head-to-tail chain of the polymer are related to its polymerization temperature, but are not related with the kind of initiators used. Therefore, poly (vinylidene fluoride) with low content of head-to-head chain (ca. 3%) can be prepared under lower polymerization temperature. Plot of content of A chain against melting points of the polymer is linear, which can be expressed by an equation: A = 24.8 + 0.362 Tm(%). |
