Patent abstract
The present invention relates to methods of forming absorbent materials and polymers used in absorbent materials, which are based upon vinyl type monomers that contain pendant carboxylic acid groups and ester group functionality. The polymers may be prepared under selected conditions of partial neutralization to provide relatively high conversions and/or relatively high values of molecular weight and/or selected amounts of repeating unit tacticity. The polymers may then be used in absorbing materials.
