&agr -OLEFIN POLYMER COMPOSITIONS AND PROCESS FOR PRODUCTION THEREOF

WIPO Patent Application WO/2004/018557

A1

An &agr -olefin polymer composition which is obtained by mixing (A) an &agr -olefin polymer, (B1) an organosilicon compound, and (C) a modified &agr -olefin polymer having a substituent reactive with a polar group and exhibiting a limiting viscosity of 0.7 dl/g or above or by bringing the components (A), (B1) and (C) into contact with each other; a modified polypropylene resin composition which is obtained by mixing (C2) a polypropylene resin having a polar group and (B) a silane coupling agent and which is specified in melt tension and MFR and has a p-xylene insolubles content of 1 wt% or below; and a process for the production of modified &agr -olefin polymer compositions, characterized by mixing a mixture consisting of (C6) a modified &agr -olefin polymer specified in limiting viscosity, Mw/Mn ratio and polar group content and (B) a silane coupling agent with (A) an &agr -olefin polymer having a limiting viscosity of 0.7 to 5.0 dl/g at an (A)/[(B) + (C)] weight ratio of 0/100 to 99/1.
