    摘要: An absorbent composition having a biodegradable absorbent polymer and a hydrophilic soft polymer surface modifying agent. The absorbent composition exhibits improved absorbency under load and gel bed permeability when subjected to an Absorbency Under Load Test and a Gel Bed Permeability Test, respectively. The absorbent composition can be made by combining a biodegradable absorbent polymer with an aqueous solution of a hydrophilic soft polymer and then drying the biodegradable absorbent polymer.

    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.
