Title:
CELLULOSE FIBER-DISPERSED POLYOLEFIN RESIN COMPOSITE MATERIAL, PELLET AND MOLDED ARTICLE USING SAME, AND PRODUCTION METHOD FOR CELLULOSE FIBER-DISPERSED POLYOLEFIN RESIN COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2019/039570
Kind Code:
A1
Abstract:
Provided is a cellulose fiber-dispersed polyolefin resin composite material obtained by dispersing cellulose fibers in a polyolefin resin containing a polypropylene resin, wherein the proportion of the cellulose fibers in 100 parts by weight of the total content of the polyolefin resin and the cellulose fibers is 1-70 parts by weight, and for the polyolefin resin, the ratio of the Z-average molecular weight Mz to the weight average molecular weight Mw obtained by gel permeation chromatography measurement satisfies Mz/Mw ≥ 4. Further provided are a pellet and a molded article that use said composite material, and a production method for the composite material.
