Abstract: This fuel tank dam closes a gap between a first structural component fixed to the inside surface of the outer plate of a fuel tank and a second structural component provided with a cutout part into which the first structural component is inserted. This fuel tank dam includes: a first portion that can be fixed to the first structural component; a second portion that has a surface extending in a direction intersecting with the first portion and can be fixed to the second structural component; and a third portion that has a bellows and is disposed between the first portion and the second portion. This fuel tank dam is configured such that the first portion, the second portion, and the third portion are integrated, the bellows has a thickness of 0.381 to 1.524 mm, and the second portion has a thickness of 0.762 to 7.620 mm.

Abstract: The present invention provides: a process for preparing a vinyl polymer containing a halogen in an amount of 1,000 mg or less per kilogram, in which a vinyl polymer containing the halogen produced by atom transfer radical polymerization of a vinyl monomer is heated at a temperature in the range of 140 to 250° C. to dehalogenate the vinyl polymer; a vinyl polymer obtained by the process; and a hydrosilylation-reactive curable composition containing the vinyl polymer.

Abstract: The present invention provides a method for producing a vinyl polymer including the steps of polymerizing a vinyl monomer by atom transfer radical polymerization with a transition metal complex as a polymerization catalyst, and bringing the resultant vinyl polymer into contact with an adsorbent in the presence of an oxidizing agent; the vinyl polymer produced by the method; and a reactive composition susceptible to hydrosilylation containing the vinyl polymer produced by the method and having at least one alkenyl group per molecule.

Abstract: A simple method for producing a powder comprising a thermoplastic elastomer composition suitable for powder slush molding is provided. This is achieved by means of a method for producing powder for slush molding obtained by pulverization of a thermoplastic elastomer, characterized in that pulverization is performed by means of the shearing action of a fixed blade and a rotating blade. In particular, a specific acrylic block copolymer and a composition thereof can be favorably used for the thermoplastic elastomer composition.
