    摘要： Hydrogenation products of copolymers prepared by ring-opening metathetical polymerisation of a cyano-substituted norbornene and at least one multicyclic olefin, which contains 95.5 to 5 wt. % of the cyano-substituted norbornene incorporated in the polymer and in which at least 60% of the initially present olefinic double bonds have been saturated by hydrogenation and the preparation of the new hydrogenation products by polymerisation in the presence of a catalyst and optionally a chain transfer agent at -20.degree. C. to 100.degree. C. at atmospheric pressure in an inert solvent, followed by hydrogenation in the presence of a homogeneous or heterogeneous hydrogenation catalyst at 0.degree. C. to 200.degree. C. under a hydrogen pressure of 2 to 200 bar in an inert solvent.

    摘要： Amorphous polymers, including homopolymers and co-polymers, containing residues of vinyl cyclohexane and/or substituted vinyl cyclohexane are described. The polymers of the present invention have a syndiotactic configuration in which the quantity of diads is greater than 50.1% and less than 74%. The polymers of the invention have high transparency, low birefringence and high heat defection temperature, and can be used to prepare molded articles (e.g., optical data storage media and lenses) and films.
