Catalyst and process for the polymerization, or copolimerização etilenicamente unsaturated organic compounds.

摘要

Process for the polymerization of unsaturated organic compound or copolimerizau00e7u00e3o etilenicamente ". A catalyst suitable for the polymerization of unsaturated compounds etilenicamente.A connecting bidentado with general formula (I): in which x = P, as, Sb, n = 0 or 1, and R ~ 1 ~ R ~ 2 ~ = alkyl, alcu00f3xi, arilu00f3xi, cicloalquila or a group (cycle) aliphatic, aromatic or olefu00ednico (cycle).Substituted or not substituted with 1 to 24 C atoms, or R ~ 1 ~ R ~ 2 ~ may form together a group cicloalifu00e1tico, cycle - elefu00ednico or aromatic substituted or not substituted, R ~ 3 ~ R ~ 4 ~ R ~ 7 ~,R ~ 8 ~ = h, alkyl, alcu00f3xi, arilu00f3xi, cicloalquila or a group (cycle) aliphatic, (cycle) olefu00ednico or aromatic, substituted or not substituted with 1 to 24 C atoms.And if n = 1: R ~ 5 ~ and / or R ~ 6 ~ = h, alkyl, alcu00f3xi, arilu00f3xi, cicloalquila or a group (cycle) aliphatic, (cycle) olefu00ednico or aromatic, substituted or not substituted with 1 to 24 C atoms.And C 'and C' 'together with R ~ 3 ~ R ~ 6 ~ may form a group (cycle) aliphatic, (cycle) olefu00ednico or aromatic, substituted or not substituted, R ~ 4 ~ and R ~ 5 ~ are absent in this case.Or (C 'and C' 'may form a link olefu00ednica, R ~ 4 ~ and R ~ 5 ~ are absent in this case, with a source of cations of a metal of group 8, 9 or 10 of the periodic table of the elements.And an acid having a pKa of less than 4.
