ABSTRACT:
An aqueous polymer composition comprising 10 to 40 wt % of a polymer in water, the polymer consisting essentially of 20-90 wt % .alpha.,.beta.-ethylenically unsaturated carboxylic acid monomer, 10-80 wt % one or more softening monomers, the aqueous composition being adjusted to pH 4-6 with alkali metal hydroxide or alkaline earth metal hydroxide and further containing 0.1 to 3 wt % zirconium crosslinking salt. Such aqueous compositions can be applied to nonwoven and woven substrates to make superabsorbent products.
