发明名称 FLEXIBLE TRANSPARENT SYNDIOTACTIC POLYPROPYLENE COMPOSITION
摘要 PROBLEM TO BE SOLVED: To provide polypropylene compositions capable of giving excellent molded products well-balanced with respect to transparency, impact resistance, flexibility, heat resistance, mar resistance and the like. SOLUTION: Polypropylene compositions comprise (i) a syndiotactic polypropylene and (ii) an ethylene/α-olefin copolymer containing 50-99 mol% ethylene component units and 1-50 mol% 4-7Cα-olefin derived component units (A) (provided the sum of the component units of copolymer (ii) is 100 mol% at a weight ratio [(i)/(ii)] of component (i) to copolymer (ii) of 95/5 to 10/90, and the copolymer (ii) having an intrinsic viscosity [η], measured in decalin at 135 deg.C, of 0.01-10 dl/g and a molecular weight distribution by GPC of not greater than 4.
