Abstract: The process for drying aqueous dispersions of a polymer (B), in which the dispersion contains, as auxiliary drying agent, at least one polymer (A) containing (in polymerised form) 80-100 wt.% monomer(s) (a) of formula CH2CR1C(O)XCR2R3-R4-SOH (I) or salts thereof and 0-20 wt.% other radically polymerisable monomer(s) (b), in which R1-3 = H or 1-3 C alkyl; R4 = 1-5 C alkylene; and X = O or NH. Also claimed are: (i) the polymer powder containing (A) and (B); (ii) the mineral binder containing such polymer powder(s); (iii) the synthetic resin-plaster drying preparation containing such powder(s); (iv) the aqueous polymer dispersions of (B) with an emulsifier content of not more than 2 wt.%, containing (A) with a Mw of 5000-35,000 as added dispersant; (v) the process for the radical aqueous emulsion polymerisation of ethylenic monomers, in which (A) with a Mw of 5000-35000 is added before, during or after polymerisation; and (vi) the polymer powder obtained by drying as above.

Abstract: Binders comprising at least one aqueous polymer dispersion with a minimum film-forming temperature less than 10 degrees C are prepared by radical aqueous emulsion polymerisation of monomer mixtures that contain the following components :(A) 45-70 parts by weight at least one monomer whose homopolymer has a glass transition temperature (Tg) less than 20 degrees C ; (B) 30-55 parts by weight at least one monomer whose homopolymer has a Tg greater than 50 degrees C ; (C) 0-1 part by weight at least one monomer with acidic groups ; and (D) 0-2 parts by weight at least one extra monomer chosen from amides, alpha , beta -unsaturated 3-6C carboxylic acids (or their hydroxy-(2-6C alkyl)-esters) and/or N-vinyl lactams. Low emission, solvent-free coating materials containing at least one of these binders are also claimed.
