Abstract: An object of the present disclosure is to provide an adhesive composition for an organic fiber which has excellent heat-resistant adhesiveness that allows an organic fiber and a rubber composition to maintain high adhesive force even when being exposed to high temperatures. An adhesive composition for an organic fiber contains: (a) an epoxy compound that is a sorbitol polyglycidyl ether and has a chlorine content not greater than 9.6% by weight; and (b) a blocked isocyanate.

Abstract: The present invention aims to provide a water-absorbing resin crosslinking agent which is excellent in safety and which can effectively crosslink a water-absorbing resin at low temperatures to produce a water-absorbing agent having a high water absorption capacity. The present invention also aims to provide a water-absorbing agent produced by crosslinking a water-absorbing resin with the water-absorbing resin crosslinking agent, and a method for producing the water-absorbing agent. The present invention may include a water-absorbing resin crosslinking agent containing a halohydrin compound having one halohydrin group represented by the following formula (1) in its molecule: wherein A represents a single bond or an alkylene group; R1 represents a hydrogen atom or an alkyl group; and X represents a chlorine atom or a bromine atom.

Abstract: An object of the present invention is to provide a process capable of producing a self-assembling peptide derivative that is useful in the fields of regenerative medicine and surgery in large quantities and in an economical and efficient manner. In particular, provided is a production process employing a combination of (i) a step of convergently constructing a sequence with use of a common repeating unit consisting of a specific amino acid sequence and (ii) a step of first isolating the peptide derivative as a disulfuric acid salt, a tetramethanesulfonic acid salt or a tetra(trifluoroacetic acid (TFA) salt), and then subjecting the peptide salt to a salt exchange reaction to yield a tetrahydrochloric acid salt.

Abstract: An object of the present invention is to provide an adhesive agent composition for an organic fiber, the adhesive agent composition having high adhesive force and not requiring the use of epoxy resin that is high in manufacturing cost. The present invention relates to an adhesive agent composition for an organic fiber, the adhesive agent composition containing a halohydrin compound and a blocked isocyanate compound and also relates to a method of treating an organic fiber, the method including the step of treating the organic fiber with a treating agent containing the adhesive agent composition and a resorcin-formalin-rubber latex (RFL).
