Abstract: Flexible laminates are prepared using a room temperature curable, water-borne laminating adhesive. The adhesive consists essentially of a copolymer emulsion of an alkyl acrylate, alkyl methacrylate, styrene or vinyl ester, or mixtures thereof, and an ethylenically unsaturated carboxylic acid, and optional selected comonomers, combined with an epoxy resin emulsion and a polyfunctional amine. The flexible laminates are characterized by rapid room temperature curing, high bond strength, superior heat resistance and chemical and water resistance.

Abstract: A sustained release, reservoir-type subcutaneous implant device for the sustained administration to a subject of a biologically active compound comprises:an effective amount of a biologically active compound;an amount of a solid hydrophilic polymer sufficient to cause swelling of the device by osmotic pressure after implantation;an effective amount of a solubilizing agent; anda sufficient amount of a non-porous rate-controlling membrane which completely encapsulates said biologically active compound, wherein said rate-controlling membrane is permeable to said biologically active compound, but is impermeable to said solubilizing agent. This device is particularly advantageous for the administration of growth promoting compounds to livestock.
Abstract: Enzymes and other biologically produced materials are recovered from the fermentation broth or other liquor in which they are provided initially and simultaneously distributed throughout particles of a polymeric matrix by dissolving the polymer in the liquor, dispersing the resultant polymer solution in a non-aqueous liquor in the presence of a stabiliser, and azeotroping the dispersion to produce either dry beads or a dispersion of small particles in the non-aqueous liquid.

The compositions also exhibit improved physical properties.
Abstract: A method is provided for reducing the force required to move a pipe through a J-tube attached to an offshore platform by coating the pipe with hydrophilic polymer and then moving the pipe through the J-tube, or by introducing a solution of hydrophilic polymer and water into the J-tube and then moving the pipe through the J-tube.
Abstract: A thermosetting resin containing composition can be heated to reduce its viscosity and used as a liquid in a liquid injection molding method. It has a phenolic resin content of about 80% to about 90% solids by weight, and contains about 5% to about 40% of a polyglycol. The composition may also contain resorcinol as a compatibilizing agent and a polyalkylene glycol as the polyglycol agent. In a novel method the resin containing composition is heated to reduce its viscosity and introduced into a heated mold in a liquid injection molding method.

Abstract: A topical agent and method for the treatment and prevention of pseudofolliculitis barbae, commonly known as "razor bumps", is effected by the topical application to beard areas of the face of a combination of acetylsalicylic acid, corn starch, isopropyl alcohol, and aloe vera.
Abstract: A solid composite air freshening article is provided which comprises a granular foam phase dispersed throughout a gelled phase in an amount effective to provide a sustained release of an effective amount of volatile air freshening ingredients present in both the foam and gelled phases. The foam phase comprises granules of a hydrophilic, polyurethane foam incorporating a volatile air freshening ingredient, a surfactant, and a solid filler material, while the gelled phase comprises water, a gelling agent, an organic solvent, and the same or a different air freshening ingredient as the granular foam phase.
Abstract: A hair conditioning composition which when applied to color-treated hair prior to perming with formulations based on thioglycolate or sulfite minimizes the reduction in tensile strength of the hair comprising about 0.1 to about 4.0 weight-percent of a water-dispersible dialkyl (C.sub.12-18) dimethyl ammonium halide; about 0.1 to about 2.5 weight-percent of alkyl (C.sub.12-18) dimethyl benzyl ammonium halide; about 0.1 to about 2.0 weight-percent of a homopolymer of diallyl dialkyl ammonium halide; optionally a thickener, a moisturizer, an emulsifier, a protein conditioner, a preservative, a colorant, and/or a perfume; and the remainder to 100 weight-percent water; and a method of conditioning color-treated hair therewith.
