Abstract:
A shaped sealing material for electrical/electronic appliances which is free from dust particle adhesion thereto and is easy to handle although it is a sealing material obtained by forming a pressure-sensitive adhesive layer on a foam. A layer comprising a pressure-sensitive adhesive composition having a storage modulus of 20 N/cm2 or higher is formed on a surface of a finely cellular foam to constitute a sealing material having an adhesive force of 5.0 N/20 mm width or higher.

Abstract:
Biomimetic adhesive compositions can be used in various aspects of subterranean treatment operations. Methods for treating a subterranean formation can comprise: providing an adhesive composition that comprises a first polymer comprising a plurality of monomers that comprise a phenolic moiety, a biopolymer that is crosslinkable with the first polymer, a crosslinking agent, and an oxidizing agent; introducing the adhesive composition into a subterranean formation; and forming a coacervate-bound surface in the subterranean formation by crosslinking the first polymer.

Abstract:
A process for the production of compounds which contain at least one urea group and at least one silyl group. The process involves reacting a compound containing at least one amino group and a carbamate compound. The compounds produced by this process are useful as surface coating compositions, foams and adhesives.
Abstract:
A novel thermally reworkable anisotropic conductive adhesive composition for attaching a semiconductor device to a substrate is provided. The composition comprises (a) a thermally reworkable crosslinked resin produced by reacting at least one dienophile having a functionality greater than one and at least one 2,5-dialkyl substituted furan-containing polymer, and (b) at least one electrically conductive material present in an effective amount to provide a conducting medium in only one direction.
Abstract:
A pregellable adhesive containing several polymers, of which at least one is olefinically unsaturated and the other capable of curing by esterification, prepared in such a way that it cures by two different chemical reaction mechanisms which can be activated successively and catalyzed at least substantially independently of one another.
Abstract:
The invention provides inherently tacky, polymeric, organic, solvent-insoluble, solvent dispersible, elastomeric, pressure sensitive adhesive microspheres having pendant hydrophilic polymeric or oligomeric moieties having a degree of polymerization greater than or equal to 2. The microspheres which are sterically stabilized can offer enhanced stability against coagulation caused by alkali, alkali salts, polyelectrolytes and repeated freeze/thaw cycles. The present invention also provides pressure-sensitive adhesives comprising these microspheres including aerosol spray PSAs, coated sheet materials prepared therefrom, and method of making the microspheres.
