    Abstract: An improved denture fixative composition comprising an adhesion promoter and a highly cross-linked copolymer of a lower alkyl vinyl ether and maleic anhydride or acid is disclosed wherein at least 65.0% of the total number of initial carboxyl groups in the copolymer are reacted. The cross-linking agent employed in this invention is calcium cation and optionally up to about 30.0% of the calcium function can be replaced with other inorganic cross-linking agents or polyhydroxy compounds either singly or in combination. The adhesion promoters are chelating agents such as polycarboxylic acids, hydroxycarboxylic acids, aminocarboxylic acids, polyphosphoric acids and their alkali salts.

  • Patent number: 5612397
    Abstract: The composition having wet state clarity includes an aqueous latex binder combination of polymer particles with a diameter of less than 80 nanometers and a thickener. When glitter flakes are dispersed in these novel compositions in their wet state, they glitter more than conventional glitter compositions. Thus, they are more appealing to a consumer or an artist than conventional glitter compositions that tend to be cloudy or dull in their wet state.

  • Patent number: 5521234
    Abstract: A Fluidized Polymer Suspension (FPS) thickener comprising a hydroxyethylcellulose and/or alkyl or arylalkyl hydrophobically modified hydroxyethylcellulose added continuously to an aqueous dispersion increases productivity for manufacture of aqueous coating compositions. The FPS can be stored and metered without delays associated with dry powders. A latex paint is continuously produced by simultaneously or sequentially mixing latex binder, dispersed pigment and FPS thickener along with other ingredients.

  • Patent number: 5504123
    Abstract: Cellulose ether derivatives comprising a hydrophobic substituent having an unsaturated alkyl portion are disclosed. The unsaturation in the alkyl portion of the hydrophobic substituent can promote crosslinking of the cellulose ether derivative. The cellulose ether derivatives are useful as ingredients in latex compositions. The cellulose ether derivatives can provide associative thickening and rheological properties to latex composition during storage and application. In addition, after the latex composition is applied to the surface to be coated, the cellulose ethers of the present invention can promote crosslinking of the latex film to provide a hard and durable coating. Latex paint compositions comprising the cellulose ether derivatives of the present invention are also disclosed.

  • Patent number: 5466731
    Abstract: Fiber or film of water-absorbent water-insoluble fibrous material has a matrix of a crosslinked copolymer formed from 50 to 95% by weight of ethylenically unsaturated carboxylic monomer and 5 to 50% by weight of copolymerisable ethylenically unsaturated monomer. The matrix contains regions of a dispersed polymeric material, the matrix copolymer and the dispersed polymeric material being mutually immiscible and chemically substantially nonreactive under ambient conditions. The fiber or film can be produced by extruding a solution or dispersion of the polymeric material in a solution of the matrix copolymer in its non-crosslinked state into a gaseous environment.
