| titleOfInvention | Polymerization process employing metal halide catalyst and polymer produced |
| abstract | A polymerization catalyst system is formed by producing a solution of a halide of scandium, yttrium, or a rare earth metal and an alcohol; contacting the solution with a halide ion exchanging source to form a solid. The catalyst thus produced can be combined with an organometallic cocatalyst. Polymers with multimodal molecular weight distribution are produced when a diol is used to prepare the catalyst and an organoaluminum halide is used as cocatalyst. Polymers with broad molecular weight distribution of the unimodal type are produced when using a trialkylaluminum compound or an alkyl aluminum hydride. |
