Zusammenfassung:An absorbent binder composition is provided which is capable of spontaneous crosslinking after application to a substrate, at a temperature of about 120°C or less. The absorbent binder composition includes a monoethylenically unsaturated polymer, such as carboxylic acid, sulphonic acid, or phosphoric acid, or salts thereof, or a quarternary ammonium salt, and an acrylate or methacrylate ester that contains an alkoxysilane functionality, or a monomer capable of co-polymerization with a compound containing a trialkoxy silane functional group and subsequesnt reaction with water to form a silanol group. The absorbent binder composition is particularly suitable for use in manufacturing a wide variety of absorbent articles. A method of making the absorbent binder composition includes preparing a monomer solution, adding the monomer solution to an initiator solution which can also contain monomer, and activating a polymerization initiator within the initiator solution.A flexible absorbent binder composition is also provided which is capable of spontaneous crosslinking after application to a substrate, at a temperature of about 120°C or less. The flexible absorbent binder composition includes about 15 to about 99.8% by mass monoethylenically unsaturated polymer units, about 0.1 to about 20% by mass polyacrylate ester units having an alkoxysilane functionality, and about 0.1 to about 75% by mass of polymer units selected from polyolefin glycols and polyolefin oxides. The flexible absorbent binder composition can be prepared using a template polymerization process, with the preformed polyolefin glycol or polyolefin oxide serving as a template polymer.
