Abstract
An improved and novel animal litter is described utilizing alumina, aluminosilicates or coal residues as the substrate intimately mixed with monomers containing acid functionalities which are polymerized in-situ. The resulting mixture is then extruded into pellets of any size or shape. Animal litter pellets prepared by this invention have vastly improved water adsorption properties, deodorizing capacity, and they do not have to be cured at high temperatures.
Claims22
An animal litter composition being selected from a group consisting of coal residue, alumina, aluminosilicate and mixtures thereof, said composition mixed and polymerized in-situ with a monomer or monomers containing at least one acidic functional group present in the molecule.
A process for preparing animal litter comprising:
- mixing one material from a group consisting of a coal residue or an aluminosilicate mineral with a monomer or monomers containing functional acidic groups;
- adding water and a free radical initiator;
- polymerizing said monomer or monomers;
- pelletizing the resulting polymerized mixture;
- and subjecting the pellets to a drying step.
