PROPYLENE COMPOSITION, PROCESS FOR PREPARING THE SAME, POLYPROPYLENE COMPOSITION, AND MOLDED ARTICLES |
摘要 |
<p>A polypropylene composition for the production of various molded articles which are excellent in moldability, mold shrinkage factor on molding, rigidity, flexibility, impact resistance, in particular low-temperature impact resistance, transparency, gloss, stress-whitening resistance, and the balance thereof; various molded articles having the above properties; a propylene composition which is suitable for a base resin for the polypropylene composition; and a process for the production thereof. The propylene composition comprises a propylene homopolymer and a propylene-ethylene copolymer, the intrinsic viscosity of the copolymer (Ä eta ÜRC) is in the range of 1.7 to 2.8 dl/g, the intrinsic viscosity ratio of the homopolymer to the copolymer (Ä eta ÜRC/Ä eta ÜPP) is in the range of 0.7 to 1.2 and a product Ä(WPP/WRC) x (Ä eta ÜRC/Ä eta ÜPP)Ü of the weight ratio (WPP/WRC) of the homopolymer to the copolymer and the intrinsic viscosity ratio thereof is in the range of 1.0 to 3.0.</p> |
