| titleOfInvention | Improvements in the polymerisation of alpha, beta-unsaturated olefines with two to four carbon atoms |
| abstract | C2 to C4 olefins, e.g. ethylene and propylene, are polymerized with or without an inert solvent and using as catalyst an oxide of Ti, Zr, Hf or Th containing less oxygen than corresponds to the formula MeO2 wherein Me is the metal. Carriers and other metal oxides may be present and specified are active carbon, aluminium oxide, pumice, silicon dioxide, magnesium oxide, calcium oxide, boron oxide, copper oxide, iron oxide and manganese oxide. The catalysts may be obtained by reduction, e.g. TiO2 or titanium phosphate reduced by hydrogen or a metal of Group Ia, IIa or IIIb, or by oxidation, e.g. Ti+TiO2 or MnO, or by a combination of oxidation and reduction, e.g. Ti+ZrO2. Optionally the catalysts may be treated with BF3, SiF4, AlCl3, FeCl2 or ZnCl2. In examples the catalysts used also are ground to a finely divided state; octane and steam are used in the purification of the products. Specifications 823,307, 825,306 and 849,855 are referred to. |
