Method for preparing filled polyolefin resins and the resin made therefrom

摘要

The detrimental effect of inorganic metal fillers on impact strength of polyolefin resins is substantially reduced by the addition of a copolymer of ethylene and an alpha-, beta-ethylenically unsaturated carboxylic acid, such as ethylene-acrylic acid, to a melt blend of the polyolefin resin containing the inorganic filler. The addition of the ethylene copolymer provides an effective means to compatibilize or couple the filler into the polyolefin resin.
