Disclosed are compositions suitable for use as a litter for the accumulation of animal urine comprised of at least one uncalcined clay substrate, said substrate characterized by having a calcium oxide content of less than about 5% by weight and wherein the clay mineral component of said substrate contains at least about 35% by weight attapulgite, combined with at least one chemical pH indicator which provides a visual indication of pH change. Also disclosed are processes for making such compositions and to litters using such compositions.

Compositions for use as diagnostic animal litter and methods for their

Intumescent amine-aldehyde copolymer compositions having improved UV stability are obtained by incorporating about 0.5-75% by weight of a polyol polyacrylate or polyol polymethacrylate into an intumescent composition comprising a low molecular weight, water-insoluble amine-aldehyde copolymer consisting essentially of repeating units which correspond to the formula: wherein Q is the residue of an alkanal containing 1-5 carbon atoms and R is hydrogen, alkyl, haloalkyl, alkoxy, haloalkoxy, halo, nitro, acetamido, or sulfonamido. The preferred compositions are those in which the amine-aldehyde copolymer is a sulfanilamide-formaldehyde copolymer and the polyol ester is a liquid ester.

Intumescent composition

Intumescent amine-aldehyde copolymer/epoxy resin compositions having improved UV stability are obtained by incorporating about 0.5-75% by weight of a polyol polyacrylate or polyol polymethacrylate into an intumescent composition comprising (A) a low molecular weight, water-insoluble amine-aldehyde copolymer consisting essentially of repeating units which correspond to the formula: wherein Q is the residue of an alkanal containing 1-5 carbon atoms and R is hydrogen, alkyl, haloalkyl, alkoxy, haloalkoxy, halo, nitro, acetamido, or sulfonamido and (B) an epoxy resin. The preferred compositions are those in which the amine-aldehyde copolymer is a sulfanilamide-formaldehyde copolymer, the epoxy resin is a liquid glycidyl ether epoxy resin, and the polyol ester is a liquid ester.
