    摘要： An absorbent cellulose material having an application of superabsorbent polymer adhered to the cellulose material. In particular, the cellulose material has an application of pre-superabsorbent polymer adhered to the material, wherein an aqueous solution of pre-superabsorbent polymer is applied to the cellulose material and converted to superabsorbent polymer upon subjected to heat for a sufficient time. The absorbent cellulose material has a fluid retention of greater then 2 g/g.

    摘要： A flexible superabsorbent binder polymer composition including a monoethylenically unsaturated polymer, such as carboxylic acid, sulphonic acid, or phosphoric acid, or salts thereof, and an acrylate or methacrylate ester that contains an alkoxysilane functionality, or a monomer capable of co-polymerization with a compound containing a trialkoxysilane functional group and subsequent reaction with water to form a silanol group wherein the flexible superabsorbent binder polymer composition has a residual monoethylenically unsaturated monomer of less than about 1000 ppm. The flexible superabsorbent binder polymer composition is particularly suitable for use in manufacturing absorbent articles. A method of making the flexible superabsorbent binder polymer composition includes preparing a monomer solution, adding the monomer solution to an initiator system, and activating a polymerization initiator within the initiator system.
