Polymerization catalysts and processes therefor

   
   

Novel catalyst systems which comprise diimine nickel complexes comprising additional ligands selected from the group consisting of acetylacetonate, hexaflourylacetylacetonate, halogens and mixtures thereof can be used with methylaluminoxane in slurry polymerization processes to polymerize mono-1-olefins and, optionally one or more higher mono-1-olefin comonomer(s), to produce high molecular weight polymers.

Os sistemas do catalizador da novela que compreendem os complexos niquelar do diimine que compreendem ligands adicionais selecionaram do acetylacetonate, do hexaflourylacetylacetonate, dos halogênios e das misturas consistindo do grupo disso podem ser usados com methylaluminoxane em processos da polimerização da pasta polimerizar mono-1-olefins e, opcionalmente um ou mais comonomer(s) mais elevados de mono-1-olefin, produzir polímeros elevados do peso molecular.
