<p>A modified polypropylene composition comprising: (A) modified polypropylene partially or wholly graft modified with unsaturated carboxylic acid or derivative thereof, in an amount of from 40 to 92% by weight, (B) amorphous or low-crystalline ethylene/ alpha -olefin copolymer having a melt flow rate (MFR, ASTM D 1238, 230 DEG C, load of 2.16 kg) of from 0.01 to 10 g/10 min and a density (ASTM D 1505) of 0.900 g/cm<3> or less, in an amount of from 5 to 30% by weight, and (C) styrene elastomer in an amount of from 3 to 30% by weight, wherein the modified polypropylene (A) is obtainable by graft modification of propylene homopolymer and/or propylene/ alpha -olefin random copolymer containing constituent units derived from alpha -olefin other than propylene in amounts of 10% or less by mol based on 100% by mol of total constituent units derived from propylene and constituent units derived from alpha -olefin other than propylene.</p> |
