Multilayer films and adhesive tapes that include such films, wherein the multilayer films include plasticized polyvinyl chloride and optionally one or more fillers.

Multilayer films and adhesive tapes

Adhesive tapes include a plasticized polyvinyl chloride backing, a primer including an ethylene/carbon monoxide-containing terpolymer and a styrene-containing block copolymer and an epoxidized polymer, and an adhesive.

Adhesive tapes

A pressure sensitive adhesive comprising the polymerization product of a reaction mixture comprising: (a1) one or more (meth)acrylate ester monomers; (a2) one or more hydrophilic monomers; and (b) non-reactive, ionic surfactant. Also, articles comprising such adhesives and methods for making such adhesives and such articles.

Wet and dry surface adhesives

A pressure sensitive adhesive comprising the polymerization product of a polymerizable composition comprising: (a) one or more (meth)acrylate ester monomers; (b) one or more hydrophilic non-acidic monomers; and (c) reactive, ionic surfactant. Also articles comprising such adhesives and methods for making such adhesives and such articles.

The present disclosure generally relates to non-conformable thermoplastic pavement marking tapes comprising a backing and an adhesive layer adjacent to the backing. In some embodiments, the backing includes an ionic copolymer. In other embodiments, the non-conformable backing has an inelastic deformation of less than 10% at 25&#xb0; C. In some embodiments, the pavement marking tape is heat-moldable.

Thermoplastic pavement marking tapes

Adhesive tapes include a plasticized polyvinyl chloride backing, a primer including an ethylene/carbon monoxide-containing terpolymer and a styrene-containing block copolymer, and an adhesive.

Adhesive tapes include a plasticized polyvinyl chloride backing, a primer including an ethylene/carbon monoxide-containing terpolymer, and an adhesive.

The present application provides a primer composition, a method for treating a wet or damp surface with the primer composition, and a method to improve the adhesion of pavement markers to wet or damp surfaces. The primer composition comprises about 5 weight percent to about 90 weight percent of the reaction product of: (i) about 30 to about 70 parts by weight of an (meth)acrylate ester wherein the (meth)acrylate ester; (ii) about 70 to about 30 parts by weight of a hydrophilic acidic comonomer; and (iii) about 10 to about 100 parts based on 100 parts of the sum of the (meth)acrylate ester and the hydrophilic acid comonomer, of a plasticizer; dissolved in about 10 to about 95 weight percent of at least one organic solvent.

Wet or damp surface preparation compositions

The present invention relates to a laminate and an article comprising a retroreflective layer having a retroreflective viewing surface and an opposing surface and a tear resistant film disposed on the retroreflective layer. The finished article is preferably flexible and suitable for use as roll-up signs, flags, banners and other retroreflective articles requiring similar flexibility including other traffic warning and personal safety items.

Retroreflective laminate comprising a tear resistant film

The invention is directed toward a hot melt adhesive composition and processes for producing the same. The hot melt adhesive composition comprises: at least one non-thermoplastic hydrocarbon elastomer; at least one thermoplastic additive, wherein a ratio of melt viscosity of the at least one thermoplastic additive to melt viscosity of the at least one non-thermoplastic hydrocarbon elastomer is less than about 1:20 when measured at a shear rate of 100 seconds at a particular hot melt processing temperature; and at least one modifier.

Thermoplastic additives for hot melt adhesives based on non-thermoplastic hydrocarbon elastomers

An alkali dispersible article comprises a sheath-core microfiber. The sheath layer comprises a hydrolytically degradable polymer, and the core layer comprises another polymer that is different than the sheath polymer. The core polymer may be a hydrolytically degradable polymer or more preferably a water soluble polymer.

Dispersible compositions and articles of sheath-core microfibers and method of disposal for such compositions and articles

A pressure-sensitive adhesive comprising a blend of at least two components, wherein the first component is at least one pressure-sensitive adhesive and the second component is at least one thermoplastic material, wherein the components form a blended composition having more than one domain and, wherein one domain is substantially continuous (generally, the pressure-sensitive adhesive) and the other domain is substantially fibrillous to schistose (generally, the thermoplastic material). The second component can be (a) at least one thermoplastic elastomer, (b) at least one elastomer with a tackifying resin or (c) at least one elastomer.

Blended pressure-sensitive adhesives

An incise drape suitable for use in surgical procedures. The drape comprises a substantially transparent flexible film that has at least a portion of one major surface coated or covered with a pressure sensitive adhesive, and a two liners removably covering the adhesive. Each liner has a handle spaced from the opposite side edges of the film, and a body portion attached to the handle. The body portion of each liner extends along the adhesive from handle in the direction away from the other liner. The drape is repeatedly folded over from the opposite side edges of the film toward the handles so that the drape may be unfolded and the adhesive exposed by pulling the handles apart.

Surgical incise drape

Multilayer microfibers of at least one layer of a hydrolytically degradable polymer and at least one layer of a water soluble polymer are disclosed. The articles have water resistance during preparation, storage, and use with mammals but are dispersible when submersed in water at conditions of elevated temperature, elevated pH, and during a single commercial laundry cycle. The articles solve both the problem of solid waste disposal prevalent with single use garments and the problem of repeated cleansing and recycling of multiple use garments. Contamination associated with the articles of the invention after their use will be disinfected during the commercial laundry cycle that is utilized to disperse the article.
