Abstract: A hot melt adhesive is described which possesses superior properties for the construction of disposal soft articles and more specifically disposable soft articles which may be exposed to moisture for prolonged periods of time. The adhesive composition includes about 10% to about 60% by weight of a butene-1-ethylene copolymer; about 20% to about 80% by weight of a tackifying resin; about 5% to about 30% by weight of a plasticizer; and about 0.1% to about 3% by weight of an antioxidant, wherein the ingredients total 100%, by weight, of the entire adhesive composition.

Abstract: Hot melt construction adhesives are described which possess superior properties for the construction of disposable soft articles. The adhesive compositions include an SIS copolymer containing at least about 25% styrene, a compatible tackifying resin, a plasticizing oil and an effective amount of a stabilizer.

Abstract: An improved wood glue containing polyvinyl acetate also contains a cross-linking catalyst comprised of aluminum chloride and a dicarboxylic acid, such as oxalic acid. The catalyst also may contain a polyvinyl alcohol and an alkaline metal chloride, such as calcium chloride, to increase the amount of dicarboxylic acid that can be absorbed.

Abstract: Hot melt adhesive compositions for bonding rigid polypropylene substrates comprise intimate blends of an amorphous copolyolefin copolymer, a polyolefin wax, a rosin-based ester resin and a polybutylene copolymer.

Abstract: Certain polyethyleneimines are used to coat solid carriers used in immunoassays to improve the sensitivity of the assay over what is obtained without the coating. Use of the invention in enzyme immunoassays yields sensitivities equal to that of radioimmunoassays. A post-coating is also used after the solid carrier has had a layer of capture molecule applied and before the assay is performed, to improve even further the sensitivity, reliability and dynamic range of the assay results.

Abstract: Adhesive compositions useful for use with medical devices, such as adhesive tapes, consist essentially of a homogeneous mixture of one or more polyisobutylenes or blends of one or more polyisobutylenes; a tackifying resin; a styrene copolymer; mineral oil; a water insoluble, water swellable, synthetic hydrocolloid which forms a gel when wet; and, an ethylene vinyl acetate copolymer which increases the dimensional stability of the final composition.

Abstract: A vinyl acetate ethylene copolymer adhesive obtains the production of a corrugated paperboard product at ambient temperatures without the need for the heat inputs heretofore required. The adhesive is foamed to expand it so that less adhesive material is required to a given quantity of product.

Abstract: A method for manufacturing a corrugated paperboard product having a two layer or dual arch corrugated medium applies a vinyl acetate ethylene copolymer adhesive in the foamed state to one entire side of one of the webs of the medium. The webs are passed through heated corrugating rolls to join them together. A liner is applied to one or both sides of the dual arch medium.

Abstract: A hot melt adhesive especially useful for producing PET bottle assemblies comprises a blend of: (1) a block copolymer selected from the class consisting of: (a) A-B-A block copolymer where A is a monovinyl aromatic hydrocarbon and B is either a conjugated diene or a rubbery mono-olefin and (b) a teleblock copolymer comprising molecules having at least three branches radially branching out from a central hub, each said branch having polystyrene terminal blocks and a butadiene segment in the center; (2) an ethylene/vinyl acetate copolymer; (3) a tackifying resin which serves to extend the adhesive properties of the system; (4) a stabilizer; and (5) a wax or oil diluent. PET bottle assemblies prepared using the above adhesive compositions are more resistant to separation than those prepared with prior art compositions not containing the ethylene/vinyl acetate copolymer.
