The present invention provides an aliphatic polycarbonate that can be thermally decomposed (dewaxed) at a relatively low temperature. The aliphatic polycarbonate comprises a constituent unit represented by formula (1):
wherein R1, R2, and R3 are identical or different, and each represent 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; R4 represents a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 20 carbon atoms; and n is an integer of 0 to 3.
本发明提供了一种可在相对较低温度下热分解(脱蜡)的脂肪族聚碳酸酯。这种脂肪族聚碳酸酯包括由式(1)表示的组成单元:
其中 R1、R2 和 R3 相同或不同,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;R4 代表具有 1 至 20 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;n 为 0 至 3 的整数。
