    摘要： The present invention relates to a method of coating substrates, especially those with a hydrophobic surface, in which the substrate to be coated is coated with a coating composition whose binder is a formulation comprising an aqueous polymer dispersion in which the polymer has carbonyl or oxirane groups (component a)), and at least one compound having at least two NH.sub.2 groups per molecule, is applied to the substrate to be coated �sic!. It also relates to coating compositions including such binder formulations, and furthermore to a method of sealing using a sealing composition including such formulations as its binder.

    摘要： Low molecular weight polymers of acrylic esters which are suitable for use as external plasticizers in coated compositions on a synthetic resin basis are obtainable by subjecting(a) from 80 to 100% by weight of at least one acrylic ester of C.sub.1 -C.sub.8 -alkanol (monomer I) and(b) 0 to 20% by weight of one or more other copolymerizable monomers (monomer II)to a free radical polymerization in a solution in isopropanol in a pressure vessel at 130.degree.-140.degree. C. by introducing first from 70 to 95% by weight of a solvent and adding the remainder of the polymerization batch continuously over 3-7 hours in separate portions of which one contains the monomers and, after the polymerization has ended, distilling off the solvent under reduced pressure, the weight proportion of solvent being 5-15% by weight based on the monomers, the weight proportion of initiator being 0.5-3% by weight based on the monomers, and the half-life of the initiator at the polymerization temperature being from 10 seconds to 3 hours.

    摘要： A process for the preparation of aqueous epoxy resin dispersions, wherein an epoxy resin having more than one 1,2-epoxide group per molecule is reacted with from 1 to 30% by weight, based on epoxy resin, of a protective colloid, containing basic nitrogen and having an amine number of from 10 to 90, in the presence of from 50 to 1,000 mole percent, relative to the amount of basic nitrogen in the protective colloid, of an acid, and in the presence or absence of one or more organic solvents, at from 50.degree. to 150.degree. C., the reaction product is dispersed by adding water, and any organic solvent present is distilled off. The novel aqueous epoxy resin dispersions are used, for example, to produce coatings.
