Polymer composition, absorbent composition, their production and use

An absorbent polymer composition comprising:

• (A) 70-99.99%-wt. of at least one component A, wherein said component A is a water-soluble or water-swellable polysaccharide or polysaccharide derivative selected from the group consisting of carboxymethyl guar, hydroxyethylcellulose, hydroxypropylcellulose, carboxymethylcellulose and carboxymethyl starch, which may optionally be modified by cross-linkage, and
• (B) 0.1-30%-wt. of at least one component B, wherein said component B is a water-swellable, synthetic polymer or copolymer of polymeric subunits selected from the group consisting of (meth-) acrylic acid, (meth-) acrylonitrile, (meth-) acrylamide, vinyl acetate, vinyl pyrrolidone, vinyl pyridine, maleic acid or anhydride, itaconic acid or anhydride, fumaric acid, vinyl sulfonic acid, 2-acrylamido-2-methylpropane sulfonic acid, the amides, the N-alkyl derivatives, the N,N'-dialkyl derivatives, the hydroxyl group-containing esters, and the amino group-containing esters of said subunits, wherein 0-98%-wt. of any acid groups may be neutralized, and wherein said polymer or copolymer is cross-linked by an at least bifunctional compound,
• wherein the recited weight percentages of said components A and B are based on the total weight of components A and B, and
• (C) 0.1-30%-wt., relative to said polymer components A and B, of an organic matrix material having a melting or softening point, respectively, of below 180.degree. C., wherein said organic matrix material prevents separation and gel blocking of said absorbent polymer composition, and
• (D) 0.001 to 10%-wt., relative to said two polymer components A and B, of an ionic or covalent cross-linking agent, wherein said cross-linking agent cross-links said components A and B with each other, and
• (E) 0 to 50%-wt., relative to said polymer components A and B, of at least one anti-blocking agent.
