Title:
PROPYLENE-BASED POLYMER, METHOD FOR PREPARING SAME, PROPYLENE-BASED RESIN COMPOSITION, AND MOLDED BODY
Document Type and Number:
WIPO Patent Application WO/2019/004418
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a propylene-based polymer having high stereoregularity at an unprecedented level, and having high heat resistance and high rigidity. This propylene-based polymer satisfies requirements (1)-(4) and preferably satisfies requirement (5): (1) the meso-average chain length is 800-100000; (2) the MFR is 0.5-1000 g/10 minutes; (3) the ratio (Mw/Mn) of Mw to Mn is 4.2-20 as measured by GPC; (4) 100≥A≥20×EXP(-0.01×B), where A is the proportion [wt%] of a component eluting at a temperature of 122°C or higher as measured by the temperature rising elution fractionation measurement method (TREF) and B is the melt flow rate [g/10 minutes] in requirement (2); and (5) the amount of components soluble in n-decane at 23°C is 0.01-2 wt%.
