    Abstract: A heat-curable aqueous coating agentcontains, as a binder, a mixture or precondensate of (A) a resin possessing basic nitrogen groups and (3) a phenol resin based on a resol ether which is bonded via o,o'-methylene ether groups and whose p-posi-tions predominantly carry hydrogen and/or methylolalkyl ether groups. After protonation with an acid, the said coating agent is particularly useful as a binder for the cathodic electrocoating of metal articles.

    Abstract: Essentially phenol-free phenol resol ethers which are bonded via o,o'-methylene ether groups are prepared by a process in which A. where the process is carried out beginning with the methylolation in an aqueous medium, the methylolation is carried out in the presence of 0.5-10% by weight, based on the phenol employed, of Me++ ions, the latter are then removed as a sparingly soluble salt, the water present as a solvent in the reaction mixture is removed at 30 DEG -80 DEG C. in the presence or absence of one or more monohydric, dihydric or trihydric alcohols and an entraining agent, and the water of reaction formed during the etherification is separated off at 45 DEG -120 DEG C., and B. where the process is carried out beginning with the methylolation in a non-polar organic solvent, the methylolation is carried out in the presence of 0.1-0.3% by weight, based on the phenol employed, of Me++ ions, the etherification is effected at 95 DEG -120 DEG C. in the presence of one or more monohydric, dihydric or trihydric alcohols, with or without recycling of the distillate which passes over, and finally residual phenol in the products prepared by A. or B. is removed by evaporation in a thin film evaporator until the phenol content is less than 1% by weight. The phenol resol ethers prepared according to the invention are useful for the preparation of coating systems and for adhesives.

    Abstract: Agglomerated polymer particles of finely divided, water-soluble or water-swellable polymers containing ammonium carboxylate groups are prepared by azeotropic removal of water from water-in-oil emulsions of the water-soluble or water-swellable polymers which contain ammonium carboxylate groups in the presence of from 0:1 to 40% by weight, based on the polymers, of polyalkylene glycols which have an agglomerating effect and which are obtainable by an addition reaction of C2-C4-alkylene-oxides with alcohols, phenols, amines or carboxylic acids and contain at least two polymerized alkylene oxide units and additionally of from 0.1 to 20% by weight, based on the polymers, of protective colloids which are obtainable by free radical copolymerization of C8-C40-monoolefins with monoethylenically unsaturated C4-C6-dicarboxylic anhydrides by a mass polymerization method at from 80 to 300° C. to give copolymers having molecular weights of from 500 to 20,000 g/mol, and said agglomerated polymer particles are used as thickeners for textile pigment print pastes.

    Abstract: Agglomerated particles of water-swellable addition polymers, the agglomerated particles having an average particle diameter of from 20 to 5000 mum and consisting of primary particles having an average particle diameter of from 0.1 to 15 mum, being preparable by polymerization of water-soluble monomers in the presence of from 1' to 10% by weight of a regulator and at least 2000 ppm, each based on the monomers, of a crosslinking agent in the manner of a water-in-oil polymerization and subsequent azeotropic removal of water from the water-in-oil polymer emulsions, containing the primary particles, in the presence of agglomerating polyalkylene glycols which(a) are obtainable by an addition reaction of C2-C4-alkylene oxides with alcohols, phenols, amines or carboxylic acids, and(b) contain at least 2 polymerized alkylene oxide units,and disintegrating into the primary particles on introduction into an aqueous medium, processes for preparing the agglomerated polymer particles and use of the agglomerated particles as thickeners for print pastes.
