POLYPROPYLENE RESIN COMPOSITION HAVING IMPROVED IMPACT STRENGTH AND HIGH TRANSPARENCY, AND ARTICLES COMPRISING THE SAME

摘要

A polypropylene resin composition, and a product containing the composition are provided to improve impact resistance and transparency by improving compatibility and dispersion of rubber. A polypropylene resin composition comprises 70-98 parts by weight of a crystalline ethylene-propylene random copolymer; at least one selected from the group consisting of 1-10 parts by weight of an ethylene-alpha-olefin-based copolymer having a specific gravity of 0.87-0.93 and 1-10 parts by weight of a propylene-ethylene random copolymer semi-rubber; and optionally 0.05-0.3 parts by weight of a nucleating agent. Preferably the nucleating agent is an organic sorbitol-based nucleating agent.
