Composite pressure sensitive adhesive microspheres are provided comprising two or more water insoluble polymers that are mixed wholly within the boundaries of polymeric microspheres. The range of monomers and polymers are chosen to tailor the properties of the composite pressure sensitive adhesive microspheres for specific performance and/or application requirements. Any polymer that can be dissolved into a solvent monomer or mixture of solvent monomers can be used to prepare the composite pressure sensitive adhesive microspheres. Pressure sensitive adhesive microspheres according to this invention can be prepared using free radical suspension polymerization.

Composite pressure sensitive adhesive microspheres

An adhesive composition is provided comprising:

Partially crosslinked microspheres

A method of making a pressure sensitive skin adhesive sheet material whereby a coating medium involving a liquid and a polymer is applied to a base layer of a polymer, and the liquid is allowed to diffuse into the base layer.

Method of making a pressure sensitive skin adhesive sheet material

A novel topical medicinal composition is described which comprises a copolymer which has both pendant fluorochemical groups and pendant polysiloxane grafts.

Polysiloxane-grafted copolymer topical binder composition with novel

A water-insoluble polysaccharide hydrogel foam and a method and article of preparing a homogeneously foamed hydrogel from a two component aqueous system of water-soluble polysaccharides bearing pendant carboxylate groups. The hydrogel foam, when it incorporates an antimicrobial, has particular utility as a surgical preparation for vaginal or rectal surgery.

Water-insoluble polysaccharide hydrogel foam for medical applications

A method and article useful for preparing stable polysaccharide gels from aqueous solutions of water-soluble polysaccharides bearing pendant carboxylate groups. The gels produced may be of the foamed or nonfoamed variety.

Form-in-place polysaccharide gels

Chromophoric-moiety-containing, polymeric materials, containing at least one fluoroaliphatic radical, which are useful as dyes or colorants for fluorine-containing liquids, as coatings or components of coatings which are colored, light-absorbing, or fluorescing and characteristic properties of flurocarbon polymers, e.g. chemical inertness and hydrophobicity; and a method of detecting leaks in normally sealed devices, e.g. electronic devices, using a coating which includes the polymeric material, and a bath of fluorine-containing liquid in which the coating is soluble.

Fluorine- and chromophore-containing polymer

This invention relates to adhesives, surface modifying compositions, sealing compositions, and topical binder compositions comprising a copolymer having a vinyl polymeric backbone with grafted pendant siloxane polymeric moieties and especially to a method of topically applying such coating to animals.

This invention relates to non-pressure sensitive topical binder compositions comprising a copolymer having a vinyl polymerica backbone with grafted pendant siloxane polymeric moieties and to a method of topically coating animals therewith.

Polysiloxane-grafted copolymer non-pressure sensitive topical binder

Disclosed is a novel composition which is a non-pressure-sensitive adhesive at room temperature (20.degree. C.) and which contains a copolymer which has pendant polysiloxane grafts. Also disclosed are applications to the hair or body of an animal containing the novel composition.

A novel composition which can serve as a pressure-sensitive or non-pressure sensitive adhesive at room temperature (20.degree. C.) and which comprises a vinyl polymeric backbone with grafted pendant siloxane polymeric moieties. Also disclosed are topical binder compositions containing the novel composition.

Polysiloxane-grafter copolymer topical binder composition with novel

A novel composition useful as an adhesive at room temperature (20.degree. C.) and which comprises a copolymer which has both pendant fluorochemical groups and pendant polysiloxane grafts. Also disclosed are topical applications containing the novel composition.

A dimensionally stable alginate hydrogel foam wound dressing that absorbs wound exudate without any appreciable swelling. The wound dressing is formed-in-place in the wound cavity or on the wound surface from a reactive composition that foams as it gels. The water-insoluble alginate hydrogel foam based wound dressing is made by mixing together the ingredients of a two component system; applying the resulting composite liquid mixture to a wound site; and allowing the composite mixture to react. One component contains an aqueous suspension of certain di-or trivalent metal salts and an effervescent compound. The second component contains an aqueous solution of a biocompatible, water-soluble acid. At least one compound, and preferably both, contain a water soluble alginate.

Wax-base or emollient-base cosmetic compositions may be provided as samples on paper carrying sheets by providing the paper with materials that prevent absorption of oleic materials and providing the cosmetic compositions with a lower sheet that is oleophobic. A binder layer of an oleophilic wax or polymer is used between said paper and the cosmetic composition.
