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), Rand Rindependently represent hydrogen, acryloyloxy [CH═CH—C(O)—O—] or (methacryloyloxy)ethyleneoxy [CHCH═CH—C(O)—O—CH—O—], with the proviso that Rand Rare 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.

Cyclic olefin copolymer, curable composition, composite product and laminate

An oligomer (2,6-dimethylphenylene ether) is provided. Its structure is shown as follows: which comprises separately independent hydrogen; alkyl or phenyl; separately independent &#x2014;NR&#x2014;, &#x2014;CO&#x2014;, &#x2014;SO&#x2014;, &#x2014;CS&#x2014;, &#x2014;SO&#x2014;, &#x2014;CH&#x2014;, &#x2014;O&#x2014;, null, &#x2014;C(CH)&#x2014;, or and a hydrogen, The features of the cured products include a high glass-transition temperature, a low dielectric feature, preferred thermal stability, and good flame retardancy. The present invention effectively controls the number-average molecular weight of the product to obtain excellent organic solubility.
