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