Olefine polymerization with supported catalysts |
| abstract |
Polymerization catalysts are prepared by impregnation of a silica or aluminum support with a vanadium, titanium and/or chromium salt decomposable upon calcination to the oxide, calcining the impregnated support at about 500 DEG -700 DEG C., impregnating the calcined support with a solution of aluminum hydride and heating the resultant material to about 300 DEG C.-500 DEG C. in hydrogen. The catalyst is extremely active for the polymerization of lower molecular weight olefins such as ethylene and ethylene-propylene mixtures. |
