Abstract
A cyclic olefin copolymer comprises a structural unit represented by Formula (I) and a structural unit represented by Formula (II) In the structural unit represented by Formula (II), R1 and R2 independently represent hydrogen, acryloyloxy [CH2═CH—C(O)—O—] or (methacryloyloxy)ethyleneoxy [CHCH3═CH—C(O)—O—C2H5—O—], with the proviso that R1 and R2 are not both hydrogen. The present invention also provides a curable composition comprising the cyclic olefin copolymer described above, a composite product comprising a substrate and a cured product formed from the curable composition, and a laminate comprising the cured product or the composite product.
