Title:
METHOD FOR PREPARING TERPOLYMER USING, AS MONOMERS, EPOXIDE CONTAINING ELECTRON WITHDRAWING GROUP, CARBON DIOXIDE, AND EPOXIDE NOT CONTAINING ELECTRON WITHDRAWING GROUP
Document Type and Number:
WIPO Patent Application WO/2017/010752
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a terpolymer of an epoxide containing an electron withdrawing group, carbon dioxide, and an epoxide not containing an electron withdrawing group, using a heterogeneous catalyst. The method for preparing a terpolymer of the present invention facilitates the recovery and reuse of a catalyst after a reaction by using a heterogeneous catalyst as a copolymerizing catalyst, and allows the synthesis of an eco-friendly higher value-added polymer that has easily formed cross-linkage and improved fire resistance by containing an electron withdrawing group in the polymer.
