摘要： A method for reducing outgassing of a polyester composed of repeat units derived from 1,4-butanediol is melt blending the polyester with 0.2 to 2 weight percent water, based on the weight of the polyester. In addition to water, the polyester can also be blended with 0.01 to 0.5 weight percent of a quencher. The method results in formation of a polyester composition which exhibits reduced outgassing, and is suitable for molding into articles, for example an automotive headlight reflector or bezel.

摘要： Provided are: a rubber-reinforcing fiber, in which adhesion between a rubber and a fiber is enhanced and which is thereby capable of further improving the durability than before when used as a reinforcing material; a rubber-fiber composite; and a pneumatic tire using the same. The rubber-reinforcing fiber includes a core-sheath type composite fiber whose core portion is composed of a high-melting-point resin (A) having a melting point of 150° C. or higher and sheath portion is composed of a resin material (B) having a melting point lower than that of the high-melting point resin (A). The resin material (B) includes: an olefin-based random copolymer (C) and/or an olefin-based homopolymer or olefin-based copolymer (D) (excluding (C)); and a styrene-based elastomer (E) containing a monomolecular chain in which mainly styrene monomers are arranged in series.
