Title:
HIGH-STIFFNESS POLYPROPYLENE RESIN COMPOSITION HAVING EXCELLENT FLOWABILITY, HEAT RESISTANCE AND AESTHETIC APPEARANCE
Document Type and Number:
WIPO Patent Application WO/2016/085074
Kind Code:
A1
Abstract:
The present invention relates to a high-stiffness polypropylene resin composition having excellent flowability, heat resistance and aesthetic appearance such as glossiness, transparency and the like, and to an ethylene-propylene block copolymer in which a propylene homopolymer and an ethylene-propylene rubber polymer are polymerized in phases. More specifically, the present invention relates to a high-stiffness polypropylene resin composition having excellent flowability, heat resistance and aesthetic appearance, the resin composition which comprises an organometallic nucleating agent and has the molecular weight distribution of a propylene homopolymer, an ethylene content of an ethylene-propylene block copolymer, an ethylene-propylene rubber content and the unique viscosity of the ethylene-propylene rubber adjusted in the presence of a Ziegler-Natta catalyst comprising a succinate-based internal electron donor.
