脂肪族聚碳酸酯型聚氨酯大多是由酯交换或环状碳酸酯开环聚合而得的聚碳酸酯合成的，直接用ＣＯ２共聚物合成聚氨酯弹性体的报道很少。本文采用阴离子配位络合的方法，通过调节聚合，以ＣＯ２与环氧丙烷为单体合成了分子量、官能度可调节的端羟基聚碳酸亚丙酯（ＰＰＣ），... Aliphatic polycarbonate polyurethanes are mostly synthesized from polycarbonates obtained by ring-opening polymerization of transesterified or cyclic carbonates. There are few reports on the synthesis of polyurethane elastomers using CO2 copolymers directly. In this paper, the coordination of anionic coordination method, through the regulation of polymerization, with CO2 and propylene oxide as the monomer synthesized molecular weight, functionality adjustable hydroxyl-terminated poly propylene carbonate (PPC), ...
