Dispersions of superabsorbent polymers, processing thereof and articles formed from the dispersions
Abstract:
Dispersions of superabsorbent polymers are described comprising blends of polyols and super absorbent polymer. Products comprising deposits formed from such dispersions are also described. Suitable polyols can include, for example, polyethylene glycol. The dispersions can be flowed onto an absorbent sheet to form a deposit (sheeted SAP), which in some embodiments can be along a fraction of the sheet surface. Generally, the deposits are dried through a wicking process in which the polyol is wicked away from the superabsorbent polymer. The sheeted SAP can be incorporated into a final product with the deposit secured within the product. The dispersion allows for selective placement of superabsorbent polymer onto an absorbent sheet and/or in a final product. Embodiments based on coated yarns and the like are also presented.
