Zwitterionicos compounds useful as activators of complexes of metals of groups 3 to 10 as catalysts for the polymerization adicionde unsaturated compounds.Catalyst Systems for the polymerization of alpha Olefins comprising these compounds and depolymerization procedures

摘要

These are catalyst activators particularly adapted to be used in the activation of metal metal complexes of Groups 3-10 for the polymerization of ethylenically unsaturated polymerizable monomers, especially alpha-olefins. Said activators comprise a zwitterionic compound of the formula (I),L + is a proton derivative of group 15 element of the elemental journalism table, and has two hydrogen carbide substitutes from 1 to 50 carbon atoms, or a derivative loaded from group 14 element of the elemental journalism table. In this group element 14 is replaced by Three hydrogen carbide substitutes for c1-50; R1 is a discrete linking software of one to four different hydrogen atoms; R2 is a single alliance composed of one to 40 different hydrogen atoms, provided that R2 is L + - R1 under sufficient conditions and in order to balance the load of the compound;R4 is a bridge halide hydride group or a linking group of 1 to 40 different hydrogen atoms; M1 is boron, aluminum or gallium; Arf is independently in each case a monovalent fluorinated organic group containing from 8 to 100 different hydrogen atoms; Y is an element of Group 15, and Z is an element of Group 14. Polymerization processes of alpha-olefins are also proposed.
