[Also in Division C3] An olefine polymerisation catalyst composition comprises a transition metal complex (NO) a ML b Z c where M is molybdenum or tungsten; L is R'COO- or R' 3 P, R' being a saturated aliphatic or aromatic hydrocarbon radical up to 20 carbon atoms; Z is halogen; a and b are 1 or 2 and c is 1, 2 or 3 or silica or thoria promoted by and oxide or sulphide of tungsten or molybdenum or an oxide of rhenium or tellurium or alumina promoted by an oxide of molybdenum, tungsten or rhenium or by a sulphide of molybdenum or tungsten or by an alkali metal salt, an alkaline earth metal salt an ammonium or bismuth salt of phosphomolybdic acid or aluminium, zirconium, calcium, magnesium or titanium phosphate promoted by oxides or sulphides of molybdenum or tungsten or rhenium oxide, or tungsten, magnesium or beryllium phosphotungstate or silica, alumina or aluminium, zirconium, calcium magnesium or titanium phosphate promoted with molybdenum or tunsten hexacarbonyl and vanadium halides, oxyhalides, alkoxyhalides, cycloalkoxyhalides or aryloxyhalides and and mixtures with R n AlX m RAlX 2 where R is aromatic or aliphatic hydrocarbon up to C 20 with optional halogen or alkoxy substitution; X is halogen; m is 2 or 3; m is 0 or 1 and m+n is 3. |
