| titleOfInvention | Solution process for the preparation of polymers of alpha-olefins |
| abstract | A solution process, and a catalyst therefor, for the preparation of high molecular weight polymers of alpha-olefins viz. homopolymers of ethylene and copolymers of ethylene and C3-C12 alpha-olefins, is disclosed. The process is operated under solution polymerization conditions at 105-320°C. The catalyst is obtained from titanium tetrahalides, vanadium oxytriha-lides and organoaluminum compounds, in which an admixture of catalyst components is heat-treated at 180-250°C and subsequently cooled to a temperature of less than 150°C. Additional vanadium oxytrihalide is then added. The resultant ca-talyst solution is activated with an aluminum compound. The catalyst has good activity, showing superior activity to catal-ysts in which additional vanadium oxytrihalide is not added or added at temperatures above 150°C. |
