Abstract
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 <IMAGE> where R1 is hydrogen or <IMAGE> R2 is CH2=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.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
185 words
A thermosetting resin composition which comprises: (1) an unsaturated polyester resin, and (2) an unsaturated monomer mixture of a vinyl aromatic monomer and a cycloaliphatic acrylate composition comprising (A) about 60 to 95 percent by weight of dicyclopentadiene acrylate, methacrylate, or mixtures thereof (B) about 2 to 15 percent by weight of a mixture of polycyclopentadienyl acrylates of the formula ##STR8## where R is CH 2 ═CZ--C(O)--O-- Z is H, or methyl n is 1, or 2 m is 0 or 1 and when m is 0 there is a double bond present (C) about 1 to about 21 percent by weight of a mixture of the copolymers of methacrylic acid or acrylic acid with adducts of cyclopentadiene with isoprene, piperylene, or mixtures thereof, (D) about 0.05 to about 10 percent by weight of a mixture of poly acrylates having the repeating unit ##STR9## where R 1 is hydrogen or ##STR10## R 2 is CH 2 ═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.
