An ester-amide block copolymer of the formula (1):
wherein R is an aromatic hydrocarbon group with 6-20 carbon atoms and G is a residue of an aliphatic polyester, an aliphatic polycarbonate, an aliphatic polyethercarbonate or a polyorganosiloxane, and having a weight average molecular weight of 30,000 - 1,000,000. This copolymer is advantageously prepared by polycondensing an activated acyl lactam-terminated aromatic amide with a diol by a bulk polymerization procedure in a molten state.
式 (1) 的酯-酰胺嵌段共聚物:
其中 R 是含有 6-20 个碳原子的芳香烃基团,G 是脂肪族聚酯、脂肪族聚碳酸酯、脂肪族聚醚碳酸酯或聚有机硅氧 烷的残留物,其重量平均分子量为 30,000 - 1,000,000。这种共聚物可以在熔融状态下,通过大体积聚合程序将活化的酰基内酰胺端芳香族酰胺与二元醇进行缩聚而制备。
