Title:
METHOD FOR PREPARING HIGH-STRENGTH AND HIGH-TOUGHNESS THERMOSETTING RESIN-BASED COMPOSITE MATERIAL AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/011244
Kind Code:
A1
Abstract:
Provided are a high molecular weight block copolymer PS-b-PCL-b-PDMS-b-PCL-b-PS and a method for modifying epoxy resin. The block copolymer PS-b-PCL-b-PDMS-b-PCL-b-PS has a structure represented by formula I. When the block copolymer PS-b-PCL-b-PDMS-b-PCL-b-PS is used for modifying epoxy resin, the tensile strength of the epoxy resin can be greatly improved, and the toughness and dynamic rigidity can also be improved.
