Abstract: A method for removing a solvent from a hydrocarbon solvent solution of a hydrogenated block copolymer (a hydrogenation degree for double bonds of conjugated diene monomer units: 30 % or more) obtained by hydrogenating a block copolymer comprising a polymer block containing a vinyl aromatic monomer unit as a main component and a polymer block containing a conjugated diene monomer unit as another main component (vinyl aromatic monomer unit/ conjugated diene monomer unit, in weight ratio: 5/95 to 95/5), characterized as comprising (1) admixing the hydrocarbon solvent solution of a hydrogenated block copolymer with hot water to produce a dispersion comprising the solution dispersed in the hot water, and (2) introducing the dispersion to a steam stripping vessel by spraying the dispersion toward the surface of the hot water under a condition wherein the vapor pressure P1 of the dispersion and the pressure P2 of the gas phase satisfy the relationship: P1 ≥ P2 , to remove the solvent through steam stripping, thereby preparing a porous crumb.

Abstract: Disclosed are dried porous crumbs of a hydrogenated block copolymer which is obtained by hydrogenating a block copolymer comprising (a) at least one polymer block composed mainly of aromatic vinyl monomer units and (b) at least one polymer block composed mainly of conjugated diene monomer units, and which has a molecular weight of 70,000 or more. The dried porous crumbs have a water content of 1 % by weight or less and having the capability of absorbing an oil in an amount of 1.0 or more, in terms of the ratio of the weight of an oil, which is absorbed by the dried porous crumbs when the dried porous crumbs are immersed in the oil at 25 DEG C under atmospheric pressure for 1 minute, to the weight of the dried porous crumbs. Also disclosed is a method for producing the same. When the dried porous crumbs are used as a modifier in the production of a molding resin composition from a thermoplastic resin and a liquid additive, such as a softening agent or a silicone oil, a shaped article having an excellent appearance can be produced by molding the molding resin composition.

Las migas porosas secas tienen un contenido en agua del 1% en peso o menor y tienen la propiedad de absorber aceite en una proporción de 1''0 o mayor, en proporción al peso de un aceite que absorben las migas porosas secas cuando las migas porosas secas se sumergen en aceite a 25ºC a presión atmosférica durante 1 minuto, respecto del peso de los terrones porosos secos. La invención también se refiere a un procedimiento para producir el mismo. Cuando las migas porosas secas se emplean como modificadores en la producción de una composición de resina para moldeo a partir de una resina termoplástica yun aditivo líquido, y un agente reblandecedor o un aceite de silicona, se pueden producir artículos con formas que tienen una excelente apariencia y que se pueden producir por moldeo de la composición de resina para moldeo.

Abstract: PURPOSE:To obtain the titled gasket having a large current conducting area without causing the decomposition of water and the deposition of scales by fixing a diagonal net consisting essentially of polyolefin and having specified thickness and the radius of curvature of the zigzag at more than a specified value in a gasket frame as a spacer. CONSTITUTION:A diagonal net made of polyolefin and having 0.3-0.6mm thickness and >=30m radius of curvature of the zigzag is used and a current conducting part spacer 4 for a gasket frame is formed. The spacer is stuck on a site 5 on the two opposite sides of a gasket frame 1 provided with a salt passage 2 and fixed to form a gasket. Plural sheets of the gaskets are used for a dilution chamber and a condensation chamber, the gaskets are alternately assembled by using a cation-exchange membrane and an anion-exchange membrane, the assembly is temporarily tightened by a clamping frame, the assembly is set in a filter press-type electrodialyzing vessel and the whole body is clamped.

Abstract: PURPOSE:To treat uniformly a membraneous polymer without forming wrinkles and crazings, by laying the membraneous polymer on a knit of a synthetic fiber and treating it by contact with a gas or a liquid. CONSTITUTION:In treating an ion exhange membrane, a diaphragm, or other membraneous polymers by contact with a gas and/or a liquid, the membraneous polymer is laid on a knit of a synthetic fiber. The knits used may be any of weft-knitted fabrics, warp-knitted fabrics, and tubular knitted fabrics, but those knitted fabrics which are knitted on a knitting machine set at a stitch determined from the equation (wherein GG is in gauge/inch, Td is a total denier of a yarn, and 1.2 2.4, the stitch is too dense, it is difficult to spread the treating solution over the surface of a film, and the treatment can not be performed evenly.

Abstract: PURPOSE:To obtain a gasket for electrodialysis cell which is free from leakage of dialyzate and has high durability by forming net-like spacer parts forming salt liquid passing parts and a gasket frame to one body. CONSTITUTION:Belt-like bodies of vulcanized natural rubber are joined together by means of adhesive, whereby a picture frame-like gasket frame 3 of 19.6dm effective electricity conducting area is manufactured. Next, notches and holes 5 for communication of liquid are opened alternately in the broad belt-like parts at the top and bottom thereof. On the other hand, an unvulcanized natural rubber sheet added with vulcanizing agent is cut to belt-like bodies, and these are placed on the right and left ends of net-like spacers made of PP and are then hot pressured and molded by vulcanization, whereby salt liquid passing parts 4 are made. These parts are joined to the notch parts of the gasket frame. At the same time, spacers 7 are joined to the electricity conducting parts 6 of the gasket frame as well. According to this method, the gasket formed with the net- like spacers are the gasket frame into one body is obtained easily.
