Abstract: A reactive liquid crosslinking agent for use in the preparation of polymeric substances. The crosslinking agent comprises a substituted 1,3,5-triazine reacted with water, an acid alkyl sulfonate and/or phosphonate and a solidifying modifier containing an hydroxyl functional group to form a substituted 1,3,5-triazine hydrate. The reactive liquid polymer crosslinking agent has a solids content between 20-99% solids. The reactive liquid crosslinking agents (RLPC's) are useful as modifiers in the preparation of polymeric compounds which are suitable for one-component self-crosslinking adhesives, coatings and polymers used in optics, textiles, composites, casting and molding. RLPC systems containing from 1-30% RLPC provide fast single package thermosetting polymeric compounds with enhanced properties such as chemical, heat and abrasion resistance.

Abstract: This invention relates to compositions containing cyanoacrylate adhesives that are temporarily inhibited from polymerizing and curing even in the presence of activating substances, such as metals, which normally catalyze polymerization of cyanocrylate adhesive compositions. This invention also relates to compositions and methods for inhibiting polymerization and curing of cyanoacrylate adhesives.

Abstract: A method of producing cellular, reticulated structures of elastomeric materials having interconnected networks of cavities which are useable in retaining and self-metering liquids. The method of producing such microporous polymeric structure includes forming a homogeneous mixture including at least one polymeric resin, combined with void former and a polyfunctional compound. The ratio by weight between the polymeric material and the polyfunctional compound is preferably from 18:1 to 1:3. The void former, polymeric material and polyfunctional compound are preferably admixed at approximately room temperature and then shaped at low temperature. The mixture is then cooled and the void former is extracted with a suitable solvent.

Abstract: Cyanoacrylate adhesives are removed from surfaces with a composition containing acetonitrile as the active solvent. The composition may also include an inert liquid solvent or diluent, a surfactant, sodium carbonate or bicarbonate, and a thickening agent.

Abstract: The invention relates to a composition for removing cyanoacrylate adhesives from surfaces. The composition contains acetonitrile, water, a sodium carbonate, a surfactant and a filler such as ethyl cellulose, starch, bentonite, silica or aluminum octanoate.
