Document Type and Number:
WIPO Patent Application WO/2023/101004
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a novel olefin resin useful as a compatibilizer for a polypropylene resin and a polyethylene resin, a method for manufacturing the olefin resin, and an application for the olefin resin. The olefin resin (β) includes a graft-type olefin polymer [R1] having: a main chain which is constituted from a propylene homopolymer or a copolymer of propylene and ethylene and in which the content of propylene-derived structural units is 76-100 mol%, and the content of ethylene-derived structural units is 0-24 mol%; and a side chain which is constituted from an ethylene homopolymer or a copolymer of ethylene and propylene and in which the content of ethylene-derived structural units is 80-100 mol%, and the content of propylene-derived structural units is 0-20 mol%.
