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(％)。
The relationship between the polymerization conditions of vinylidene fluoride and the head-to-head chain content of the polymer was studied. Experiments show that the polymer head-head chain content and the polymerization temperature, regardless of the type of initiator. Thus, polyvinylidene fluoride with a low head-to-head structure (about 3%) can be produced by polymerization at a lower polymerization temperature. The A content of the polymer chain is plotted against its melting point in a straight line and can be expressed as the equation A = 24.8 + 0.362 T_m (%).
