Abstract
Abstract A catalyst for addition polymerization comprising (a) an (initiator) first component comprising a plurality of atoms M as hereinafter defined, each in a moiety of formula (I): MX(Y.sub.n)Z.sub.p (I) wherein M is Si, Ge or Sn n is 0 or an integer, and p is an integer such that (n+p)=3; X is a diradical ##STR1## bound via Q to M where Q is N, P, As or P(=T)G.D where T is O or S and G and D are each independently a bond, O or S, R 1 is optionally substituted hydrocarbyl, or, when Q is P, M(Y n )Z p as herein defined, R 2 is optionally substituted hydrocarbadiyl, or R 1 and R 2 together are hydrocarbatriyl, all such R 1 and R 2 being inert in the conditions of the process of the present invention; and R 2 being linked directly or indirectly to any group as defined for X, or an organic radical comprising further moieties of formula (I), or one or more M(Y n )Zp moieties as herein defined; and Y and Z are independently any group A or OA where A is optionally substituted hydrocarbyl inert in the conditions of the process of the present invention, or Y is optionally substituted trialkylsilylalkyl; and (b) a (co-catalyst) second component salt comprising an anion selected from azide, cyanide, cuanate, fluoride, bifluoride, nitrate and optionally substituted organic mono- and poly-phosphonates, -phosphinates -sulphonates, -sulphinates, -carboxylates, -siloxides and -oxides; and a cation which in use of the catalyst is inert under the polymerization process conditions yet renders the co-catalyst available in the polymerizing medium; initiator components for such catalysts, compositions comprising such components, and a polymerization process, in particular the addition polymierization of vinylic monomers, using the catalysts.
