Abstract
The invention relates to curable resin compositions based on an unsaturated prepolymer, a vinyl ether monomer that can be cross-linked with it and one or more other monomers for use as structural resins. The resin composition is cured with the aid of a radical-forming system that is unstable in the temperature range of −20° C. to +110° C., and contains an unsaturated prepolymer having an acid number of less than 10 mg of KOH per g and a vinyl ether monomer according to formula (I) or (II):A—CH═CH—O—R  (I)or(A—CH═CH—O)n—R′  (II)with A, R, R′ and n having the described meanings. The invention also relates to a process for the preparation of such resin compositions and uses thereof.
