PURPOSE:To obtain the subject composition having excellent transparency and rigidity and suppressing smoking or dirt on roll in molding containing specific organic phosphoric ester compound, metallic salt of fatty acid and methyl-butene polymer in propylene polymer. CONSTITUTION:(A) 100 pts.wt. crystalline propylene polymer is mixed with (B) 0.001-0.1 pt.wt. organic phosphoric ester compound such as 2,2'-methylene- bis-(4,6-di-t-butyl phenyl) phosphate expressed by formula I [R<1> is direct bonding, sulfur or expressed by formula II (R<4> is H or 1-4C alkyl); R<2> and R<3> are H or 1-8C alkyl], (C) 0.001-0.1 pt.wt. metallic salt of 8-26C aliphatic carboxylic acid and (D) 0.01-0.1 pt.wt. 3-methyl-1-butene polymer to afford the aimed composition. Besides, said composition is drawn in at least one direction to obtain drawn film of said composition. |
