A process for the preparation of stable dispersions of finely divided polyisocyanates, and the preparation of heat-crosslinkable isocyanate systems. Stable dispersions of finely divided polyisocyanates in a liquid which may or may not contain surfactants, protective colloids and other assistants are obtained by a method in which polyisocyanates are treated with a stabilizer in the presence of absence of the liquid, and the dispersions prepared from these are finely dispersed and/or milled under the action of high shear forces, if necessary with the addition of further stabilizer. These dispersions are useful as crosslinking agents, particularly for the preparation of heat-cross-linkable isocyanate systems.

Condensates based on substituted ureas, their reaction products with di- and/or polyisocyanates, derivatives of di- and/or polycarboxylic acids or p-substituted phenols and/or their methylol derivatives, their preparation and their use. These condensates each contain two or more cyclic urea units and can be prepared either by reacting primary di- or polyamines with ureas and reacting the product with predominantly CH-acidic aldehydes or by reacting primary amines with isocyanates and reacting the product with predominantly CH-acidic aldehydes in the presence of an acidic catalyst. The said condensates and their reaction products are useful for the preparation of heat-curable coating materials and of binders for cathodic electrocoating.

Nonaqueous polymer dispersions are obtainable by polymerization of esters (A) of acrylic acid and/or methacrylic acid and/or ethylacrylic acid with C.sub.1 -C.sub.20 -alcohols in an organic solvent or a mixture of organic solvents in which the polymers formed are insoluble, and in the presence of copolymers (B) having a molecular weight of from 500 to 20,000 and obtainable by bulk or solution polymerization of monoolefinically unsaturated monomers at from 180.degree. to 400.degree. C. and from 1 to 200 bar, and the said dispersions are used for the production of finishes, coating materials and adhesives.

Nonaqueous polymer dispersions

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.
