    摘要: Disclosed is a resin composition comprising (.alpha.) at least one polymer selected from the group consisting of a non-modified cyclic monomer unit-containing polymer and a modified cyclic monomer unit-containing polymer having a number average molecular weight of from 10,000 to 5,000,000, wherein the cyclic monomer unit is derived from a cyclic conjugated diene, and (.beta.) at least one polymer other than the polymer (.alpha.), and wherein the polymer (.alpha.) is present in an amount of at least 1% by weight, based on the total weight of the polymers (.alpha.) and (.beta.). The molecular structure of the polymer (.alpha.) which is contained in the novel resin composition of the present invention and which is selected from a non-modified cyclic monomer unit-containing polymer and a modified cyclic monomer unit-containing polymer, wherein the cyclic monomer unit is derived from a cyclic conjugated diene, can be controlled with large freedom. Therefore by combining the polymer (.alpha.) with a polymer (.beta.) other than the polymer (.alpha.), a resin composition which is excellent in various properties, such as theremal stability with respect to rigidity, and impact resistance can be provided with large freedom with respect to the choice of its properties.

    摘要: The methacrylic copolymer of the present invention is a novel copolymer having low moisture absorption properties which comprises specific proportions of methyl methacrylate units and tert-butylcyclohexyl methacrylate units, optionally with specific ethylenically unsaturated compound units copolymerizable with the above-mentioned monomer units. The copolymer of the present invention is excellent not only in colorlessness, transparency, moldability, low double refraction and heat stability but also in low moisture absorption properties and heat resistance and, therefore, is suitable for use as a material for shaped articles, such as an optical element substrate and a light transmissible extruded plate, and can particularly advantageously be used for applications, such as an optical disc substrate.
