PURPOSE:To provide a composition having excellent stamping formability and capable of giving form integrated with a singly layered or plurally layered surface by compounding a crystalline ethylene.propylene block copolymer having a specific mol.wt. distribution with an amorphous ethylenic copolymer in a specified amount. CONSTITUTION:(A) A crystalline ethylene.propylene block copolymer having a Q value of 8-50, the Q value being a barometer exhibiting a mol.wt. distribution is compounded with 1-30wt.% of an amorphous ethylenic copolymer comprising amorphous ethylene.butene copolymer or a mixture of 50wt.% of the amorphous ethylene.butene copolymer and <=50wt.% of one kind of more of polymers selected from amorphous ethylene.propylene random copolymer, etc., and, if necessary, <=50wt.% of an inorganic filler to provide a composition having a melt flow index of 1-100g/10min. |
