Estimating the term…
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 ML.sub.x B.sub.y or M[SR].sub.x B.sub.z, 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.
In a process for polymerizing epoxy compounds using a Lewis base, the improvement comprises effecting the polymerization in the presence of 0.01 to 50 parts by weight per 100 parts by weight of the epoxy compound of a Lewis base which is in the form of complex of the formula
A polymerizable mixture comprising 100 parts by weight of at least one epoxy compound of 0.01 to 50 parts by weight of a metal complex compound of the formula
