  • Patent number: 8057875
    Abstract: The present invention has its object to provide a resin composition for tubes excellent in balance among wear resistance, flexibility, gas permeation resistance and low resilience (pliability). The object is accomplished by a resin composition for tubes which comprises an isobutylene block copolymer (A) constituted of a polymer block (a) derived from isobutylene as a main constituent and a polymer block (b) derived from a monomer component other than isobutylene as a main constituent, and a thermoplastic polyurethane resin (B).

  • Patent number: 8034785
    Abstract: The present invention provides a peptide which selectively adsorbs an anti-?1 adrenoreceptor antibody being one of the contributing factors in dilated cardiomyopathy. The peptide of the invention can be immobilized on a carrier in a short period of time with rarely inducing side reactions, and adsorbent for adsorbing an anti-?1 adrenoreceptor antibody can be produced with good efficiency by using the peptide. In addition, the present invention provides an adsorbent comprising such peptide immobilized on a carrier, an adsorber wherein such adsorbent is used, and a method for adsorbing an anti-?1 adrenoreceptor antibody. The adsorbent and adsorber according to the invention can efficiently deprive an anti-?1 adrenoreceptor antibody-containing liquid, in particular body fluid, of the antibody.

  • Publication number: 20100234801
    Abstract: Disclosed is a resin composition for balloons, which is excellent in gas permeation resistance and hydrolysis resistance (acid resistance), while having an excellent balance among flexibility, mechanical strength and elastic recoverability. Also disclosed is a balloon made of such a resin composition for balloons. Specifically disclosed is a resin composition for balloons, which is characterized by containing an isobutylene block copolymer (A) having a polymer block (a) mainly composed of isobutylene and a polymer block (b) mainly composed of an aromatic vinyl monomer. This resin composition for balloons is also characterized in that the polymer block (b) is 10-40% by weight of the weight of the isobutylene block copolymer (A).
