Ethylene/alpha-olefin copolymer and process for preparing the same |
| abstract |
The ethylene/alpha-olefin copolymer of the invention is a copolymer of ethylene and an alpha-olefin of 6 to 8 carbon atoms and has the following properties: the melt tension (MT) and the melt flow rate (MFR) satisfy the following relation 9.0xMFR<-0.65> > MT > 2.2xMFR<-0.84>, the flow activation energy ((Ea)x10<-4> J/molK), the carbon atom number (C) of the alpha-olefin in the copolymer and the alpha-olefin content (x mol%) in the copolymer satisfy the following relation (0.039Ln(C-2)+0.0096)xx+2.87 < (EA)X10<-4> <= (0.039Ln(C-2)+0.1660)xx+2.87, and the haze (Haze) of an inflation film produced from the copolymer satisfies the specific conditions. The ethylene/alpha-olefin copolymer according to the invention have excellent moldability and can produce films of excellent transparency and mechanical strength. |
