Abstract:
An initiator composition for polymerizing unsaturated monomers, comprising a component (A) which is a mixture ofi) at least one salt of a metal in the second sub-group of the periodic table, optionally in solution in an aromatic solvent or in an .alpha.,.beta.-unsaturated ester, andii) at least one salt of a metal in the seventh and eighth sub-group of the periodic table, optionally in solution in an aromatic solvent or in an .alpha.,.beta.-unsaturated ester; anda component (B) which is at least one organic peroxy ester, wherein the components (A) and (B) are kept separate from one another until they are brought together to initiate polymerization of the unsaturated monomers.
