Title:
GRAFT COPOLYMER CONTAINING EPOXY GROUP AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/121138
Kind Code:
A1
Abstract:
Disclosed in the present invention are a graft copolymer containing an epoxy group and an application thereof. The graft copolymer is a polymer containing an epoxy group and a side chain of a high molecular copolymer, and is mainly formed by means of the free radical polymerization of 40wt%-90wt% of a monomer A containing a carbon-carbon double bond, 5wt%-30wt% of an unsaturated monomer B containing an epoxy group and 5wt%-30wt% of a high molecular polymer C containing a carbon-carbon double bond. The preparation process is as follows: first, a high molecular polymer D is obtained by using free radical copolymerization, the high molecular polymer C containing a carbon-carbon double bond is then prepared by using a reaction between groups, and the graft copolymer containing an epoxy group is finally obtained by carrying out free radical copolymerization and drying devolatilization on the obtained high molecular polymer C, the monomer A and the monomer B. The graft copolymer containing an epoxy group of the present inventionmay be used as a compatibilizer for polymer blends and a chain extender for polymers.
