Accelerator compositions for the curing of unsaturated maleic, vinylic, allylic and epoxy-type polyesters, are disclosed. The accelerator compositions comprise a complex of a salt of a metal selected from lithium, vanadium, copper, nickel, magnesium, iron and cobalt, and a nitrogen-containing compound capable of forming a complex with these metal salts and being selected from ammonia, ammonium salts, amines, amides, heterocyclic nitrogen compounds and their adducts with anhydrides and epoxides. Also disclosed are a curable composition comprising resin and the accelerator composition of the invention and a curing process carried out in the presence of an accelerator composition of the invention. |
