Abstract

Disclosed is a propylene polymer composition comprising (a) a propylene polymer, (b) an olefin type elastomer and (c) a polar group-containing olefin polymer composition obtained by heating (c-1) an olefin polymer containing a carboxyl group or an acid anhydrous group in its molecule and (c-2) an amino compound, each in a specific amount. Also disclosed is a propylene polymer composition comprising (a) a propylene polymer, (b) an olefin type elastomer, (c-1) an olefin polymer containing a carboxyl group or an acid anhydrous group in its molecule and (c-2) an amino compound, each in a specific amount. The propylene polymer compositions of the present invention are excellent in properties of being coated with various coatings.
