Abstract: A process for the production of low-viscosity, aqueous polymer dispersions (APD), with polymer concentrations of at least 50 vol% and viscosities of less than 1000 mPa.s, comprises radical emulsion polymerisation of ethylenic monomers (except vinyl and vinylidene halides), by the monomer addition method, in the presence of an initiator and small amounts of water-miscible organic solvent(s) (I). Also claimed are APD obtained by this process.

Abstract: In the prepn. of aq. polymer dispersions (I) by free radical aq. emulsion polymerisation of vinyl monomer(s), the cloud pt. of the nonionic emulsifier (II) used is below the polymerisation temp. Also claimed are (I) contg. (II) with a cloud pt. below 70 deg C. Pref. the feed process is used and all (II) is present in the polymerisation vessel or (II) is added before and/or during polymerisation.

Abstract: A process for the preparation of stable aqueous polymer dispersions which contain an alkenyl-aromatic compound as copolymerized units, by polymerizing monomer mixtures which contain (a) not less than 2% by weight of an alkenyl-aromatic compound and (b) from 0.5 to 10% by weight of an ethylenically unsaturated C3-C5-carboxylic acid and/or its amide and/or its nitrile and/or an ethylenically unsaturated monomer containing sulfonic acid groups, with or without (c) acrylic acid esters, methacrylic acid esters and/or butadiene in aqueous emulsion in the presence of a polymerization initiator, with or without an emulsifier and with or without a polymerization regulator, at a pH below 7, in the presence of from 0.2 to 2% by weight of formaldehyde.

Abstract: The paper/cardboard is treated with an anionic or non-ionic aq. dispersion of a film-forming copolymer comprising 15-60 wt.% of the nitrile of an alpha, beta-olefinic unsatd. carboxylic acid and other olefinic unsatd. monomers having an average polymer particle size of 0.025-0.2 mu. Pref. dispersion also contains 1-20 wt.% based on amt. of copolymer, of a water soluble alpha, beta-olefinic unsatd. carboxylic acid polymer that contains >=15 wt.% of the carboxylic acid.
