Title
(EN) NOVEL ALIPHATIC POLYCARBONATE
(ZH) 新型脂肪族聚碳酸酯
Abstract
(EN)
Provided is an aliphatic polycarbonate resin that can be used as a thermally decomposable binder capable of thermal decomposition (degreasing) at low temperature. The aliphatic polycarbonate is an aliphatic polycarbonate containing a structural unit represented by formula (1) (in the formula, R1, R2, and R3 are the same or different and represent a hydrogen atom, an optionally substituted C1-15 alkyl group, or an optionally substituted C6-20 aryl group, R4 represents an optionally substituted C1-20 alkyl group or an optionally substituted C6-20 aryl group, and n represents an integer of 0 to 3).

(ZH)
本发明提供能够用于可在低温下热分解(脱脂)的热分解性粘合剂的脂肪族聚碳酸酯树脂。该脂肪族聚碳酸酯为包含式(1)(式中,R1、R2和R3相同或不同,表示氢原子、可被取代基取代的碳原子数1~15的烷基或者可被取代基取代的碳原子数6~20的芳基,R4表示可被取代基取代的碳原子数1~20的烷基或者可被取代基取代的碳原子数6~20的芳基,n表示0~3的整数)所表示的结构单元的脂肪族聚碳酸酯。
