発明の名称 (英語) NON-COVALENT BONDING SOFT ELASTOMER AND PRODUCTION PROCESS THEREFOR UPDATE
発明の概要(英語) This non-covalent bonding soft elastomer comprises a two-component block copolymer consisting of at least one chain A and at least one chain B and a solvent, wherein the chain B has functional groups capable of non-covalent bonding and the solvent is a nonvolatile liquid in which the chain A does not dissolve but the chain B dissolves and which combines with the functional groups of the chain B by non-covalent bonding.
従来技術、競合技術の概要(英語) BACKGROUND ART
The polymeric material is intimately involved with our daily lives and, in the various fields in a material are essential. Of the polymeric material, a material having flexibility at room temperature the polymer gel as the elastomer and the like. The polymer gel and is, for a network-forming polymer chain is a soft material containing solvent. For contain large amounts of solvent, the normal expansion and contraction ability not shown, as the material is fragile. On the other hand, the elastomer and is, in the same manner as the polymer chains have a net structure of the polymer gel is without solvent, at room temperature molten state network chain rubber elasticity to the soft material. The elastomer fluid when heated and shows, upon cooling a parameter representing the elastomeric behavior referred to as a thermoplastic elastomer. Chain A glassy state at room temperature, the molten state at room temperature and the chain B ABA tri-block copolymer thermoplastic elastomer are typical.
ABA triblock copolymer of the thermoplastic elastomer in order to improve the mechanical properties, in recent years non-covalent (hydrogen bond, ionic bond or the like) pseudo-crosslinking has been introduced into the study. Of the pseudo cross-linking may be non-covalent supramolecular cross-linking, that temporarily or weak cross-linking of the cross-linking can also be called soft, incorporating such a super-molecular crosslinking supramolecular elastomer is an elastomer (elastomer or simply non-covalent) can be referred to.
The inventors of the present invention, the tri-block copolymer ABA B of paying attention to the central chain, self-organization of the tri-block copolymer ABA used as a base, the central chain melting B self-complementary hydrogen bonding functional group was introduced into the supramolecular elastomer produced, the reported mechanical properties (for example non-patent document 1, reference 2). By this supramolecular elastomer tensile measurements, than prior to the introduction of functional groups of the toughness after the introduction, it was confirmed that a large elongation at break becomes.
Of the central chain B ABA triblock copolymer with attention paid to research reports by way of example, the preparation of the aqueous polymer gel (hydrogel) may be used (for example see non-patent document 3). In non-patent document 3, a water-soluble B central chains ABA triblock copolymer hydrogel is immersed in the aqueous solution of metal salt, to prepare a expansion ability to the hydrogel. The hydrogel may be prepared in water 2 between the central B chain divalent metal ions by an ionic interaction for supramolecular crosslinking, a low elastic modulus and have an ability of the decompressed. An elastomer was not possible to realize a low elastic modulus and cannot be realized with the present hydrogel, elastomer can be used as a material that is different from the considered new dynamics.
