- carboxylic acids preferably acrylic acid and / or methacrylic acid and esters of these acids with monohydric alcohols having 1 to 4 C atoms in the molecule
- the monomers are polymerized either alone or as a mixture with one another in an aqueous medium in the presence of customary polymerization initiators and customary emulsifiers or, in the preferred embodiment of the present invention, in the presence of the triblock copolymers described (from PIBSA and PEO).
- customary polymerization initiators and customary emulsifiers or, in the preferred embodiment of the present invention, in the presence of the triblock copolymers described (from PIBSA and PEO).
- PIBSA and PEO triblock copolymers
- amphphilic block copolymers When using the amphphilic block copolymers - either in the preparation of the aqueous polymer dispersions or adding the triblock copolymers to an aqueous polymer dispersion which has already been stabilized with other emulsifiers - stable aqueous polymer dispersions or polymer emulsions are obtained. They contain, based on polymer, 0.1 to 70% by weight, preferably 0.5 to 20% by weight, of at least one amphiphilic block copolymer. However, conventional emulsifiers can be added to these polymer dispersions for further modification. The parts given in the examples are parts by weight, the percentages are percentages by weight, unless the context indicates otherwise.
- the paper coating color was composed as follows:
- Acronal® S 201 is a binder based on a copolymer of butyl acrylate and styrene, 1.0 part of Na stearate, and
- the solids content of the paper coating slip was adjusted to 49% by adding water and the pH to 9.4 to 9.6 with sodium hydroxide solution.
- a wood-free coating base paper from Scheufeien GmbH + Co.KG, D-73250 Lenningen, with a basis weight of 70 g / m 2 was used as the base paper.
