Provided is an aliphatic polycarbonate applicable to the production of a block copolymer by radical polymerization. The aliphatic polycarbonate is represented by formula (1):
wherein R1, R2, R3, and R4 are identical or different, and each represents a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 15 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 20 carbon atoms; A and B are identical or different, and each represents a substituent that serves as an initiating group for living radical polymerization, a hydroxy group, an alkoxy group, an acyloxy group, or a carboxy group, provided that at least one of A and B is a substituent that serves as an initiating group for living radical polymerization; and m is an integer of 10 to 2500.
本发明提供了一种脂肪族聚碳酸酯,适用于通过自由基聚合生产嵌段共聚物。该脂肪族聚碳酸酯由式(1)表示:
其中 R1、R2、R3 和 R4 相同或不同,且各自代表氢原子、具有 1 至 15 个碳原子的取代或未取代的烷基或具有 6 至 20 个碳原子的取代或未取代的芳基;A 和 B 相同或不同,各自代表作为活自由基聚合引发基的取代基、羟基、烷氧基、酰氧基或羧基,条件是 A 和 B 中至少有一个是作为活自由基聚合引发基的取代基;以及 m 是 10 至 2500 的整数。
