MANUFACTURE OF POLYETHYLENES |
| 摘要 |
Blends of two or more polyethylenes are made by reacting ethylene with an oligomerization catalyst that forms alpha -olefins, and two polymerization catalysts, one of which under the process conditions copolymerizes ethylene and alpha -olefins, and the other of which under process conditions does not readily copolymerize ethylene and alpha -olefins. The blends may have improved physical properties and/or processing characteristics.
