Abstract: Storage-stable aq. polymer dispersions are claimed, which are obtd. by dispersing a mixt. of: (a) 15-50 (wt.) copolymer (A) of 1.5-15% 3-10C comonomer (I) contg. a carboxylic acid or anhydride gp., 30-98.5% 1-20C alkyl (meth)acrylate (II), 0-60% vinyl-aromatics (III), 0-20% copolymerisable carbonyl cpds. (IV) and 0-20% other organic comonomers (V) and (b) 50-85% copolymer (B) of 40-100% (II) and 0-60% (III), (IV) and/or (V), in water, with addn. of NH3 and a polyhydrazide (C). (A) and (B) together contain up to 65% units of (II), which forms a homopolymer with Tg below 0 deg.C and (A) and/or (B) contains (IV) units. The claims also cover the prodn. of the dispersions. A soln. of a mixt. of (A) and (B) in an organic solvent is prepd. by prepg. one copolymer in the soln. obtd. by polymerisation of the other, then the mixt. is dispersed in water, with addn. of NH3, excess solvent is distilled off if necessary and then (C) is added, pref. in an amt. of 0.1-1 equiv. (C)/equiv. carbonyl gps. in the (A+B) mixt.

Abstract: Polymeric compositions which undergo crosslinking after drying at room temperature or elevated temperatures and are dissolved or dispersed in water are prepared by reacting polymeric organic compounds containing carbonyl and carboxyl groups with polyhydrazides in the presence of monoketones or monoaldehydes and are dissolved or dispersed in water by partially or completely neutralizing the carboxyl groups. They are useful as crosslinking agents and as binders for coatings on sheet-like substrates.
