    Abstract: An improved anhydrous denture adhesive is prepared to contain a mixture of a cationic polymeric material and an anionic protein material as the adhesive ingredient. The mixture may be formulated as a powder or anhydrous paste, which, when applied to dentures and exposed to moisture, develops superior adhesive properties. Suitable cationic materials include at least one of the following: copolymers of substituted or unsubstituted acrylamide with vinyl quaternary ammonium salts; copolymers of substituted or unsubstituted acrylamide with vinyl and alkyl substituted vinyl pyridinium salts; and an 0-lower alkyltrimethylammonium chloride-substituted-anhydroglucose polymer. As the anionic component there may be used at least one protein material, such as soybean meal, sunflower seed meal or peanut meal.

    Abstract: Non-ionic water-soluble cellulose ethers modified with 3-azido-2-hydroxypropyl groups bound via an ether link are provided having a molar degree of substitution MSAHP in the range from 0.001 to 0.50. Exemplary cellulose ethers are alkyl celluloses, including methyl, hydroxyalkyl (e.g. hydroxyethyl or hydroxypropyl) or alkylhydroxyalkyl cellulose (e.g. methylhydroxyethyl). Reaction products with alkyne compounds are also provided, resulting in a terminal alkyne group. The reaction of azide with the alkyne proceeds as a 1,3-dipolar cycloaddition reaction, advantageously with Cu(I) or ruthenium catalysts. A multiplicity of cellulose ethers can be obtained from the conversion reaction. Variations in the macroscopic properties can be achieved by controlled modification, ranging from increased or reduced viscosity. The reaction, taking place within a few seconds, requires only minimal catalyst. Gel formation is reversible by adjustment of the pH such that a monophasic system (high-viscous fluid) arises again from a biphasic system (gel+low-viscous water phase).

    Abstract: The present invention is directed to a method for producing a cured tire filling composition and the composition resulting from such a method. The A component has from about 3 to about 30 weight % of a polyisocyanate comprising polymeric toluene diisocyanate (TDI) or diphenylmethane diisocyanate (MDI) with an average functionality of 2 or greater, from about 10 to about 60 weight % of a high molecular weight polyol or blend of polyols having a hydroxyl number in the range of about 20 to about 56, and the balance of a plasticizer. The amount of plasticizer is an amount sufficient to lower the NCO content of the resulting. A component to be less than 10% and is in the range of from about 10 to about 80 weight %. The B component has from 0 to about 30 weight % of the high molecular weight polyol or blend of polyols, from about 70 to about 99 weight % added water, from about 1 to about 8 weight % of a hydrophilic moiety, and from about 0.1 to about 5 weight % of a catalyst. The resulting elastomer is cured to produce an elastomeric tire filling composition within a pneumatic tire casing having a Durometer hardness in the range of about 5 to 60 (Shore A).
