Abstract:
Provided is an adhesive as follows. The adhesive can bond/secure an adherend to a support with maintaining high adhesiveness during the existence of the need for securing of the adherend to the support, even in a high-temperature environment or in an environment with abrupt temperature change. The adhesive enables debonding of the adherend from the support without breakage of the adherend when the securing becomes unnecessary. The adhesive can be easily removed when remained on the adherend after debonding. The adhesive according to the present invention contains (A) a multivalent vinyl ether compound, (B) a compound including two or more of a constitutional unit represented by Formula (b), and (C) a thermoplastic resin. In the formula, X is selected from hydroxy and carboxy.
Abstract:
Water-soluble triazabutadiene molecules and methods for producing and using such compounds. The triazabutadiene molecules may be more labile at pH levels below physiological pH, such as pH 7, pH 6, pH 5, etc. The triazabutadiene molecules and compounds may be used for depositing diazonium salt and/or cargo in a pH-sensitive manner. The triazabutadiene molecules may alternatively be cleaved in reducing conditions or as a light-catalyzed reaction. The compounds herein may be used for delivery of drugs, as part of detection systems, or for other applications such as underwater adhesive applications.
Abstract:
This invention provides an adhesive agent with a stronger adhesive force that can adhere and be peeled reversibly with the irradiation of light. With the use of a liquid crystalline polymer compound containing azobenzene or a sugar alcohol derivative containing a hydroxyl group and azobenzene, a photo-reactive adhesive agent that can strongly adhere to and be peeled from a substrate reversibly with the irradiation of light can be obtained.

In the preferred embodiment of the invention, the supply of material having discrete elements is selected from the group consisting of fibrous material, granular material, pellet material, agglomerated material, aggregated material and mixtures thereof. Also, in the preferred embodiment, the amorphous polyolefin comprises greater than about 5 wt. % wax.
Abstract:
Polymers with improved bioadhesive properties and methods for improving bioadhesion of polymers have been developed. A compound containing an aromatic group which contains one or more hydroxyl groups is grafted onto a polymer or coupled to individual monomers. In one embodiment, the polymer is a biodegradable polymer. In another embodiment, the monomers may be polymerized to form any type of polymer, including biodegradable and non-biodegradable polymers. In some embodiments, the polymer is a hydrophobic polymer. In the preferred embodiment, the aromatic compound is catechol or a derivative thereof and the polymer contains reactive functional groups. In the most preferred embodiment, the polymer is a polyanhydride and the aromatic compound is the catechol derivative, DOPA. These materials display bioadhesive properties superior to conventional bioadhesives used in therapeutic and diagnostic applications. These bioadhesive materials can be used to fabricate new drug delivery or diagnostic systems with increased residence time at tissue surfaces, and consequently increase the bioavailability of a drug or a diagnostic agent. In a preferred embodiment, the bioadhesive material is a coating on a controlled release oral dosage formulation and/or forms a matrix in an oral dosage formulation.

Abstract:
Provided are a graphite pressure-sensitive adhesive tape that is suitable for improving thermal efficiency; and a graphite pressure-sensitive adhesive tape with a release liner, which contains the pressure-sensitive adhesive tape. This graphite pressure-sensitive adhesive tape with a release liner is provided with a graphite pressure-sensitive adhesive tape, which has a first pressure-sensitive adhesive layer and a graphite layer in this order, and a release liner that protects the surface of the first pressure-sensitive adhesive layer. The first pressure-sensitive adhesive layer has a single layer structure.
Abstract:
A laminate body includes a base material, a film-like or a membrane-like undercoat layer that is formed in at least a portion of the outer surface of the base material, and an atomic layer deposition film that is formed on a surface opposite to a surface coming into contact with the base material among both surfaces of the undercoat layer in the thickness direction thereof. At least a portion of precursors of the atomic layer deposition film bind to the undercoat layer, and the atomic layer deposition film is formed into a membrane shape covering the undercoat layer.
