摘要:
The instant invention provides a polyolefin blend composition, process for producing the same, and articles made therefrom. The polyolefin blend composition according to the present invention comprises: (a) from 75 to 97 percent by weight of one or more random propylene copolymers having a DSC melting point in the range of from 120° C. to 160° C., and a melt flow rate (MFR) in the range of from 1 to 120 g/10 minutes; (b) from 3 to 25 percent by weight of one or more ethylene ?-olefin copolymers having a melt index (I2) in the range of from 100 to 1500 g/10 minutes, a density in the range of 0.860 to 0.910 g/cm3, and a molecular weight (Mw) in the range of from 10,000 to 50,000 g/mole, wherein said ethylene ?-olefin copolymer is homogenously branched copolymer, and wherein said ethylene ?-olefin copolymer is linear or substantially linear; (c) optionally from 5 to 15 percent by weight of one or more propylene ?-olefin interpolymers having a DSC melting point in the range of less than 110° C., a heat of fusion in the range of less than 50 Joules/gram, and a crystallinity in the range of from at least 1 percent by to 40 percent by weight, and a melt flow rate in the range of less than 80 g/10 minutes.
