发明名称 PROPYLENE-ETHYLENE-BASED RESIN COMPOSITION AND CONTAINER CONSISTING OF THE SAME
摘要 <p><P>PROBLEM TO BE SOLVED: To provide a propylene-ethylene-based resin composition improved in the balance of stiffness and impact resistance, having a high transparency, excellent in whitening resistance, also without causing deteriorations of such as a smell etc., having less eluting components and suitable for a container of a foodstuff, a medical material, etc., and an injection-molded container. <P>SOLUTION: This propylene-ethylene-based resin composition is provided by containing (B) 0.05 to 0.7 pt.wt. nucleating agent based on (A) 100 pts.wt. propylene-ethylene copolymer consisting of (I) 86 to 93 mass% propylene-ethylene random copolymer containing 1.5 to 5.0 mass% ethylene content and (II) 7 to 14 mass% propylene-ethylene random copolymer having 15 to 35 mass% ethylene content, obtained by successive polymerization by using a metallocene-based catalyst. The container obtained by injection-molding the above propylene-ethylene-based resin composition is also provided. <P>COPYRIGHT: (C)2009,JPO&INPIT</p>
