Title:
PROPYLENE-ETHYLENE COPOLYMER RESIN COMPOSITION, AND MOLDED PRODUCT, FILM AND SHEET THEREOF
Document Type and Number:
WIPO Patent Application WO/2013/125670
Kind Code:
A1
Abstract:
This propylene-ethylene copolymer resin composition is produced by a metallocene-based catalyst and comprises: 97-65 parts by weight of a propylene-based polymer (A) wherein (A-i) the ethylene content in the polymer (A) is 0-6.0 wt%, (A-ii) the MFR of the polymer (A) is 0.1-100 g/10 minutes, and (A-iii) Mw/Mn is 2-4; and 3-35 parts by weight of a propylene-ethylene copolymer (B) wherein (B-i) the ethylene content in the copolymer (B) is 0.4-13 wt%, and (B-ii) the MFR of the copolymer (B) is 0.5-20 g/10 minutes. The copolymer (B) comprises: 65-95 wt% of a propylene-based polymer component (B1) wherein (B1-i) the ethylene content in the polymer component (B1) is 0-6.0 wt%; and 5-35 wt% of a propylene-ethylene copolymer component (B2) wherein (B2-i) the ethylene content in the copolymer component (B2) is 8-25 wt%, and (B2-ii) the MFR of the copolymer component (B2) is 0.0001-0.5 g/10 minutes.
