Abstract: A method for producing a substrate carrying a cementitious composition is provided. The method involves dispersing a mixture of an ion-leachable, inorganic compound and a poly(carboxylic acid) in a liquid to form a coating mixture wherein the liquid is selected to be a non-aqueous, non-leachable liquid in which the poly(carboxylic acid) is substantially soluble. The coating mixture is then applied to the substrate.

Abstract: A cementitious composition is provided which includes a dry ion-leachable glass powder and further includes an essentially water-insoluble non-hydroxylic polycarboxylic aromatic compound. The composition is usable in orthopedic bandages, and particularly those bandages which are activated by dipping the substrate carrying the compound into a water-containing vessel to activate the compound.

Abstract: A cementitious composition including dry ion-leachable glass powder and further including an agent for modifying the rate of setting. The agent is selected to include the d,l form of tartaric acid.

Abstract: Hydrocolloidal dispersions of random interpolymer compositions that have a capacity for absorbing water in amounts of from 10 to 125 times their own weight or greater and are also bacteriostatic are prepared by the polymerization in aqueous medium of a mixture of monomers comprising (1) up to about 90% by weight of an ester of an .alpha.,.beta.-olefinically unsaturated carboxylic acid and a monohydric or polyhydric alcohol having a terminal quaternary ammonium group and (2) at least one .alpha.,.beta.-olefinically unsaturated comonomer in the presence of a crosslinking agent comprising a difunctional monomer derived from an .alpha.,.beta.-olefinically unsaturated carboxylic acid. The interpolymer compositions can be used for binding or coating nonwoven fabrics including paper to improve water absorbency, or cast into a structurally self-supporting film.

Abstract: Surgical pressure sensitive adhesive compositions having improved long term skin adhesion characteristics comprising a polyacrylate, rubber, or polyolefin pressure sensitive adhesive and a cross-linked hydrophilic random interpolymer. The interpolymer comprises an ester of an .alpha.,.beta.-olefinically unsaturated carboxylic acid and an alcohol having a quaternary ammonium group; an .alpha.,.beta.-olefinically unsaturated comonomer; and a difunctional cross-linking monomer. The adhesive compositions are useful in surgical adhesive tapes, adhesive bandages, and like items comprising a pressure sensitive adhesive.
