Abstract

Cycloalphatic acrylate compositions and methods of making them are disclosed. The compositions are mixtures containing dicyclopentadiene (meth) acrylate and (meth) acrylates such as the mono and di (meth) acrylates of tri, and tetracyclopentadiene and a mixture of the copolymers of (meth) acrylic acid with adducts of cyclopentadiene with isoprene and/or piperylene and a mixture of poly (meth) acrylates having the repeating unit ##STR1## Where R.sup.1 is hydrogen or ##STR2## R.sup.2 is CH.sub.2 .dbd.CZ--C(O)--O-- Z is H, or methyl n is 0, 1 or 2 and m is 0 or 1 and when m is 0 there is a double bond present. The compositions are useful to make cross-linkable blends with unsaturated resins or monomers and to make laminates.
