Polypropylene resin compositions |
| abstract |
The polypropylene resin composition of the invention comprises a polypropylene resin and a rubber component in specific proportions. The rubber component comprises an ethylene random copolymer (B1) and a propylene/1-butene random copolymer (B2). The copolymer (B1) is obtained by random copolymerizing ethylene and an .alpha.-olefin of 3 to 20 carbon atoms, and has a specific density, a specific MFR and a specific crystallinity. The copolymer (B2) has a specific content of constituent units derived from propylene, a specific content of constituent units derived from ethylene, a specific MFR, a specific Mw/Mn and a specific B value (parameter indicating randomness of a copolymerized monomer sequence distribution). The weight ratio of the copolymer (B1) to the copolymer (B2) in the rubber component (B) is in the range of 95/5 to 20/80. The polypropylene resin composition can provide molded products, e.g., films, having excellent heat-sealing properties, low-temperature impact resistance, transparency and blocking resistance. |
