Title:

FILLER DISPERSIBILITY AND AFFINITY IMPROVER COMPRISING POLAR GROUP-CONTAINING PROPYLENE COPOLYMER AND COMPOSITE MATERIAL USING THE SAME

Document Type and Number:

Japanese Patent JP2007262335

Kind Code:

A

Abstract:

To provide an excellent dispersibility and affinity improver excellent in dispersibility and affinity of filler in polypropylene materials, and to provide composite materials using the improver.

The filler dispersibility and affinity improver comprises a polar group-containing propylene copolymer (A) comprising 94.9-99.99 mol% propylene unit represented by structural formula (I), 0.01-0.1 mol% polar unit represented by structural formula (II) and 0-5 mol% nonpolar unit represented by structural unit (III) and having 70,000-1,000,000 weight-average molecular weight Mw. Wherein, R1is a polar group-containing 1-20C hydrocarbon group; and R2is H or a 2-20C hydrocarbon group.
