    摘要： A thermoplastic resin composition consisting essentially of (A) 10-90% by weight of a graft copolymer (A) obtained by polymerizing a mixture of an alkenyl cyanide compound and an aromatic alkenyl compound in the presence of a butadiene rubber latex in which 40-100% by weight of butadiene rubber particles (A-1) having an average particle diameter of at least 1,300 .ANG. but less than 2,100 .ANG., 0-60% by weight of butadiene rubber particles (A-2) having an average particle diameter of 2,100 .ANG. or more and 0-20% by weight of butadiene rubber particles (A-3) having an average particle diameter other than the average particle diameters of the particles (A-1) and (A-2) are dispersed, provided that the alkenyl cyanide compound content in the resin component of the graft copolymer (A) is at least 10% by weight but less than 30% by weight, and (B) 90-10% by weight of a copolymer of an alkenyl cyanide compound with an aromatic alkenyl compound having an alkenyl cyanide compound content of 30-40% by weight, the proportion of the butadiene rubber component in the composition being 5-30% by weight. Said thermoplastic resin composition is excellent in surface appearance of molded article, shows an improved ejection whiteining during molding, and a high gloss of molded article.

    摘要： A thermoplastic elastomer molded article having a surface treated with a silicone emulsion and/or aqueous solution of silicone containing water-soluble silicone with a silicone content of 1 to 30 wt % is provided. As the thermoplastic elastomer, a composition comprising 20 to 100 wt % of 1,2-polybutadiene having a 1,2-bond content of 70% or more and a degree of crystallinity of 5 to 50% and 0 to 80 wt % of other thermoplastic elastomers, provided that the total amount of the 1,2-polybutadiene and the other thermoplactic elastomers is 100 wt %, can be given. The molded article of the present invention can be applied to various types of tubes, sheets, and hoses as well as a tube for medical use since the surface of the article has improved sliding properties and sliding wear resistance, without impairing transparency, flexibility, lightweightness, and mechanical strength.

    摘要： A resin molded article which is a molded article obtained by irradiating a resin molded article containing 100 to 60 parts by weight of (A) syndiotactic 1,2-polybutadiene having a crystallinity of 5% or more and 0 to 40 parts by weight of (B) another thermoplastic polymer with an electron beam, in which the 50% stress of the molded article after the electron beam irradiation (50% M:M2) is from 1.01 to 2.5 times the 50% stress before the electron beam irradiation (50% M:M1), and the molded article has steam sterilization resistance. The molded article is excellent in flexibility and hardness, excellent in steam sterilization resistance, and useful for medical applications such as an infusion tube, an infusion solution container, a catheter and the like.
