| abstract | A catalyst for addition polymerisation comprisingn (a) an (initiator) first component comprising a plurality of atoms M as hereinafter defined, each in a moiety of formula (I): nMX(Y n )Z p (I) nwherein nM is Si, Ge or Sn nn is O or an integer, and p is an integer such that (n + p) = 3; nX is a diradicaln bound via Q to M where nQ 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, nR¹ is optionally substituted hydrocarbyl, or, when Q is P, M(Y n )Z p as herein defined, nR² is optionally substituted hydrocarbadiyl, or nR¹ and R² together are hydrocarbatriyl, nall such R¹ and R² being inert in the conditions of the process of the present invention; and nR² 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 nY 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, cyanate, fluoride, bifluoride. nitrate and optionally substituted organic mono- and poly-phosphonates, -phosphinates -sulphonates, -sulphinates, -carboxylates. -siloxides and -oxides; and na cation which in use of the catalyst is inert under the polymerisation process conditions yet renders the co-catalyst available in the polymerising medium; ninitiator components for such catalysts, compositions comprising such components, and a polymerisation process, in particular the addition polymerisation of vinylic monomers, using the catalysts. |
