    摘要： A block copolymer mixture containing a star-branched block copolymer which mixture is excellent in the balance between transparency and impact resistance and can give molded articles which do not suffer from anisotropy and therefore exhibit improved impact resistance even when the articles are produced by injection molding under high shearing. A block copolymer mixture containing a star-branched block copolymer which mixture contains three kinds of vinyl aromatic hydrocarbon polymer blocks (S1, S2 and S3) different in molecular weight, characterized in that the molecular weight distribution of the mixture of the blocks S1, S2 and S3 falls within a specific range and that in the gel permeation chromatogram of the mixture of the blocks S1, S2 and S3, M1/M3 and M2/M3 fall within specific ranges wherein M1, M2 and M3 are the peak-top molecular weights of the blocks S1, S2 and S3 respectively.

    摘要： A block copolymer composition which is excellent in the balance between transparency and impact resistance and is improved particularly in the impact resistance of products of high-shear injection by inhibiting the products from becoming anisotropic. A block copolymer composition obtained by blending two block copolymers which are each composed of a hard segment block part consisting of a block made mainly from a vinyl aromatic hydrocarbon and a soft segment block part consisting of a block made mainly from a conjugated diene and which are specified in the structure of the hard segment block part. The molded articles made from the composition by not only extrusion or blow molding but also injection are remarkably improved in impact resistance without lowering the transparency.

    摘要： A resin composition characterized by comprising: 5 to 95 wt. % aromatic vinyl/olefin random copolymer (A) which has an aromatic vinyl content of 1 to 99 mol % and contains a head-to-tail segment composed of two or more aromatic vinyl units; and 95 to 5 wt. % α-olefin polymer (B) and/or aromatic vinyl polymer (C) (provided that it is neither a medical material nor a medical supply). The composition contains substantially no chlorine, is excellent in impact resistance, moldability, weatherability, and chemical resistance, and is suitable for use as injection moldings, extrusion moldings, films, sheets, etc. It also provides an excellent vibration damper.
