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.degree. C. to +110.degree. 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.dbd.CH--O--R (I)
or
(A--CH.dbd.CH--O).sub.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.
