| titleOfInvention | Polymerization catalyst and method |
| abstract | A catalyst system for the polymerization of at least one 1-olefin to produce a polymer of ultralow molecular weight (ULMW) and prepared by (1) forming a substantially dry intimate mixture of an alkyl ester of titanium containing about 1-7 carbon atoms in the alkyl group and a support of the class consisting of finely divided silica, alumina, zirconia, thoria and mixtures thereof, (2) calcining said ester-support mixture to and at a temperature between about 400 DEG -1000 DEG C., (3) adding to the resulting calcined mixture an organotin chromate essentially of the formula <IMAGE> wherein each R is an individually selected hydrocarbon radical containing from 1-14 carbon atoms, and (4) activating the resulting coated calcined mixture by heating to and at a temperature between about 300 DEG -500 DEG C. in the presence of oxygen. |
