Beschreibung
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. Cette invention se rapporte à une composition de liant absorbant qui est capable de réticulation spontanée après application sur un substrat, à une température d'environ 120· C ou inférieure. Cette composition de liant absorbant contient un polymère monoéthyléniquement insaturé, tel que de l'acide carboxylique, de l'acide sulfonique ou de l'acide phosphorique, ou des sels de ceux-ci, ou un sel d'ammonium quaternaire et un ester d'acrylate ou de méthacrylate ayant une fonction alcoxysilane, ou un monomère capable de copolymérisation avec un composé contenant un groupe fonctionnel trialcoxysilane et d'une réaction ultérieure avec de l'eau, afin de former un groupe silanol. Cette composition de liant absorbant est particulièrement appropriée pour être utilisée dans la fabrication d'une grande variété d'articles absorbants
