An aqueous synthetic resin formulation essentially comprising a synthetic resin A, a metallic cation with a charge number of from 2 to 4, dispersants, water, and finely divided fillers, and also, if desired, acetophenone derivatives or benzophenone derivatives, the resin A being prepared by free-radically initiated aqueous emulsion polymerization of monomers in the presence of from 0.01 to 3 parts by weight of an alien polymer seed per 100 parts by weight of the monomer mixture.

Aqueous synthetic resin preparation

Binder formulations based on aqueous polymer dispersions having a minimum film-forming temperature of below 10&deg; C. and comprising at least one binder polymer P in the form of an aqueous dispersion comprising at least one anionic emulsifier and at least one nonionic emulsifier.

Binder formulations based on aqueous polymer dispersions

Plasters, renders, masonry paints, interior paints and glazes which contain from 0.5 to 10% by weight of a distearyldiketene emulsion consisting of

Plaster, renders, masonry paints, interior paints and glazes containing

Paints and renders contain, as binders, aqueous dispersions of copolymers which have a minimum film-forming temperature of from -15.degree. to 20.degree. C. and consist of

Paints and renders containing aqueous dispersions of vinylidene

A process for the preparation of aqueous polymer dispersions which have a low film-forming temperature but still give films having a high block resistance, and the use of these polymer dispersions as binders for coating materials.

Preparation of polymer dispersions which form block-resistant films

Aqueous low-emulsifier dispersions of emulsion copolymers which contain, as copolymerized units,

Aqueous low-emulsifier dispersions of butadiene-styrene emulsion

Aqueous polyacrylate dispersions having improved flow characteristics are prepared by polymerizing esters of acrylic acid and/or methacrylic acid and alkanols of 1 to 10 carbon atoms, with or without admixture of styrene and/or vinyl esters and/or water-soluble monoolefinically unsaturated comonomers (the monomer feed being in the form of an emulsion), in aqueous emulsion in the presence of a free radical polymerization initiator, a protective colloid, a nonionic emulsifier and a regulator, at least a part of the protective colloid being introduced into an aqueous initial charge, and a water-soluble regulator being employed in the initial charge and in the feed.
