Abstract:
1. A method for producing polyethylene, comprising: obtaining a high shear mixing device; forming in said high shear mixing device a high shear mixture comprising ethylene and a polymerization catalyst dispersed in a solvent, wherein said high shear mixture comprises submicron-sized ethylene gas-containing bubbles dispersed in a liquid phase, wherein forming said high shear mixture comprises an energy expenditure of at least 1000 W/m subjecting the high shear mixture to polymerization conditions comprising pressure in the range of about 203 kPa to about 6080 kPa and temperature in the range of about 20° C. to about 230° C., whereby at least a portion of said ethylene is polymerized to form polyethylene.
