PROPYLENE-BASED POLYMER FOR INJECTION MOLDING, AND INJECTION MOLDED PRODUCT COMPOSED THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a propylene-based polymer for injection molding, having excellent transparency and impact resistance; and to provide an injection molded product composed thereof. SOLUTION: The propylene-based polymer is constituted so as to satisfy the following requirements (a) and (b): (a) a part (CXS) soluble in 20°C xylene is 5-20 wt.%; and (b) the molecular weight distribution (Mw/Mn) of the CXS measured by a gel permeation chromatography (GPC) is≥6. The injection molded product is obtained by carrying out the injection molding of the polymer. COPYRIGHT: (C)2004,JPO
