ABSTRACT:
The present invention is directed to isocyanate derivatives containing about 2 to 30% by weight of carbodiimide groups, --N.dbd.C.dbd.N--, on a statistical average at least about 0.8 carbodiimide groups per molecule, about 5 to 200 milliequivalents per 100 g of solids of chemically incorporated sulfonate groups and, optionally, 0 to about 25%, based on solids, of chemically incorporated ethylene oxide units, --CH.sub.2 --CH.sub.2 --O--, in polyether chains. The present invention is also directed to a process for the preparation of these isocyanate derivatives and to their use as additives for aqueous dispersions or solutions of plastics containing carboxyl groups or groups convertible into carboxyl groups.
