Title:
ALIPHATIC COPOLYCARBONATE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/193344
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of polymer synthesis, and specifically discloses aliphatic copolycarbonate and a preparation method therefor. The aliphatic copolycarbonate contains a structural unit as shown in formula (1) and a structural unit as shown in formula (2), wherein R1 is a C3-C10 alkylene group, and R2 is an alicyclic group. In the present invention, a specific alicyclic monomer is introduced into a molecular chain of aliphatic polycarbonate, such that a new type of aliphatic copolycarbonate is obtained. The polymer in the present invention has the properties of a relatively high melting point, a relatively high glass transition temperature, relatively high thermal stability, etc., and has relatively good thermal performance.
