Polymerizable epoxide mixtures and process using Lewis base complexes

摘要

A polymerizable mixture comprising 100 parts by weight of at least one epoxy compound and 0.01 to 50 parts by weight of a metal complex compound of the formula MLxBy or M[SR]xBz, wherein M is a metal ion of a metal of main groups II and III and sub-groups thereof of the Periodic Table, L is a chelate forming ligand selected from the group consisting of dioximes, alpha - and beta -hydroxycarbonyl compounds or enolizable 1,3-diketones, SR is an acid ion of an inorganic acid, B is a Lewis base, x is an integer from 1 to 8, y is an integer from 1 to 5 and z is an integer from 7 or 8 with the proviso that B is not a polyvalent phenolic compound and a process for the polymerization thereof.
