| titleOfInvention | Slightly crosslinked, water-swellable polymer or copolymer and a process for its manufacture |
| abstract | The polymer or copolymer is in the form of grains or powder and is made by free-radical polymerization of a reaction mixture comprising sodium acrylate, a crosslinking agent, a polymerization initiator, organic natural and / or synthetic fibers 0.05 to 2 mm in length in an amount of 2 to 10% by weight. and optionally acrylic acid. The fibers are fines of 1.0 to 10.0 dtex. The reaction mixture may contain a thickening agent, such as starch, in an amount of 0.2 to 20.0% by weight of the monomer or monomers. The initiator is, for example, ammonium peroxodisulfate in an amount of 0.1 to 0.5% by weight of the monomer or monomers. The crosslinking agent is, for example, an acrylic or methacrylic ester with a dibasic or tribasic alcohol in an amount of 0.001 to 0.5% by weight of the monomer or monomers. The polymer or copolymer is produced by applying the reaction mixture to a fiber layer and passing it through a surface heated to 90-140 ° C, then dried and further processed by breaking and grinding. |
