PURPOSE: To provide a resin composition having highly improved long running property in melt-molding and quality by compounding a saponified ethylene-vinyl acetate copolymer, a polyolefin resin, a graft polymer and a hydrotalcite solid solution. n CONSTITUTION: The objective resin composition comprises (A) a saponified ethylene-vinyl acetate copolymer, (B) a polyolefin resin, (C) a graft polymer prepared by grafting an ethylenic unsaturated carboxylic acid or a derivative thereof to a polyolefin resin and further reacting the product with a polyamide oligomer, and (D) a hydrotalcite solid solution of the formula (a front M 2+ is Mg, Ca, Sr, Ba; the next M 2+ is Zn, Cd, Pb, Sn; M 3+ is trivalent metal; A n- is n-valent anion; x, y 1 , y 2 , m are satisfied with a equality and inequalities; D<x≤0.5; 0.5<y 1 <1; y 1 +y 2 =1; 0≤m<2) in an A:B:C ratio of 60-95wt.%:45-35 wt.%:1.5-10wt.% and in a (A+B+C):D weight ratio of 100:0.01-1. n COPYRIGHT: (C)1991,JPO&Japio |
