Abstract
An absorbent binder composition is provided which is capable of crosslinking after application to a substrate, in the absence of radiation, at a temperature of about 120° C. or less. The 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 absorbent binder composition can be prepared using a template polymerization process, with the preformed polyolefin glycol or polyolefin oxide serving as a template polymer.
Claims28
An absorbent binder composition combined with water, the absorbent binder composition comprising a water-soluble ionic polymer capable of sufficient moisture-induced crosslinking within about 10 minutes at a temperature of about 120° C. or less, to reach an absorbent capacity of at least one gram per gram using the centrifuge retention capacity test.
An absorbent binder composition, comprising:
- a. about 15 to about 99.8% by mass of monoethylenically unsaturated polymer units;
- b. about 0.1 to about 20% by mass polyacrylate ester units that include an alkoxysilane functionality;
- and
- c. about 0.1 to about 75% by mass polymer units selected from the group consisting of polyolefin glycol units, polyolefin oxide units, and combinations thereof.
