POLYPROPYLENE RESIN COMPOSITION, ITS PRODUCTION METHOD AND MOLDED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a polypropylene resin composition which contains only a small amount of an odorous component and is excellent in melt tension and moldability, and to provide its manufacturing method, and a molded article prepared by using the same. SOLUTION: This composition contains a polypropylene resin comprising at least two propylene polymers different in mol.wt. and containing, as a component, a specified amount of a specific high-mol.wt. propylene polymer and a lactone-base additive having a specified structure and has an MFR of 0.1 g/10 min or higher but not higher than 10 g/10 min. A polypropylene resin composition containing the above composition and a specific radiation-treated polypropylene resin is also provided.
