Abstract:
The invention relates to a process for producing superabsorbents, comprising the preparation of partly neutralized acrylic acid by the steps (i) preparing an over-neutralized acrylic acid having a degree of neutralization of at least 100.1 mol-% by mixing of an acrylic acid 1 and a base and (ii) preparing a neutralized acrylic acid having a degree of neutralization from 50 to 85 mol-% by mixing of the over-neutralized acrylic acid and an acrylic acid 2, wherein the content of dimeric acrylic acid in the acrylic acid 2 is lower than the content of dimeric acrylic acid in the acrylic acid 1.

Claim (Index 1):
A process for producing a superabsorbent, comprising polymerization of a monomer solution, comprising\n a) partly neutralized acrylic acid, b) at least one crosslinker, c) at least one initiator, d) optionally one or more ethylenically unsaturated monomers copolymerizable with the acrylic acid mentioned under a) and e) optionally one or more water-soluble polymers, drying, grinding, and classifying the resulting polymer gel, optionally thermally postcrosslinking and cooling the resulting polymer particles, wherein the partly neutralized acrylic acid was prepared in a process, comprising i) preparing an over-neutralized acrylic acid having a degree of neutralization of at least 100.1 mol-% by mixing an acrylic acid 1 and a base, and ii) preparing a neutralized acrylic acid having a degree of neutralization from 50 to 85 mol-% by mixing the over-neutralized acrylic acid and an acrylic acid 2, wherein a content of dimeric acrylic acid in the acrylic acid 2 is lower than a content of dimeric acrylic acid in the acrylic acid 1.
