  • Patent number: 7906585
    Abstract: The invention relates to absorptive, crosslinked polymers which are based on partly neutralized, monoethylenically unsaturated monomer carrying acid groups wherein the absorptive crosslinked polymer may be coated with a thermoplastic polymer, and have improved properties, in particular in respect of their capacity for transportation of liquids in the swollen state, and which has a high gel bed permeability and compatibility to affix to a thermoplastic material.
    Type: Grant

  • Patent number: 7619131
    Abstract: The present invention provides a translucent absorbent composite having a substrate with a light transmittance of at least about 60% and a flexible superabsorbent binder polymer composition applied to the substrate. The polymer composition may be prepared from the reaction product of a monomer solution including at least 15% by mass monoethylenically unsaturated monomer selected from carboxylic acid, carboxylic acid salts, sulphonic acid, sulphonic acid salts, phosphoric acid, or phosphoric acid salts; an acrylate or methacrylate ester that contains an alkoxysilane functionality; a copolymerizable hydrophilic glycol containing an ester monomer; an initiator system; and a neutralizing agent. The unsaturated monomer is neutralized to at least 25 mol % and the flexible superabsorbent binder polymer composition has a residual monoethylenically unsaturated monomer content of less than about 1000 ppm. The absorbent composite has a light transmittance of at least 45%.

  • Patent number: 7399813
    Abstract: 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.

  • Patent number: 7335713
    Abstract: A process of making the flexible superabsorbent binder polymer composition includes preparing a preneutralized monomer solution having at least about 40 mol % degree of neutralization, preparing a monomer solution including monoethylenically unsaturated monomers, one of which includes an alkyloxysilane functionality, preparing initiator system solutions and adding the solutions to the monomer solution, mixing the foregoing solutions into a polymerization solution, cooling the polymerization solution, and post neutralizing the polymer.
