Definitions
- the present invention relates to a copolymer, a process for its preparation, the use of the copolymer, and a polymeric mixture and their use.
- water-soluble nonionic derivatives of polysaccharides are often used as rheology modifiers and water retention agents in order to delay or undesirably evaporate the undesirable evaporation of the water required for hydration and processability into the substrate prevent.
- water retention is controlled with such additives.
- additives also have a decisive influence on the consistency (plasticity), smoothness, segregation, stickiness, adhesion (on the substrate and on the tool), stability and slip resistance as well as adhesive pull and compressive strength or shrinkage.
- US-B-6,187,787 and US-A-2004/024154 describe high molecular weight sulfo-containing polymers which exhibit good water retention properties. These polymers have in common that they are polyelectrolytes with a net anionic charge.
- the aim is to set particularly short curing times in order to ensure early accessibility (about 5 hours) of the laid tiles even at low temperatures (approx. 5 ° C).
- This is achieved by extremely high dosages of salts acting as accelerators, for example calcium formate.
- high salt loads especially divalent cations are critical
- the polymers according to US-A-2004/024154 lose much of their effectiveness.

Also, these show in building material systems both at low, as well as high salt load insufficient water retention properties.
- hydrophobically modified cationic copolymers even in combination with anionic surfactants in building material systems, do not show adequate thickening and completely inadequate water retention properties.

- composition of gypsum plaster is shown in Table 3.
- composition of the test mixture (in% by weight)
- the test results in Table 4 show that the copolymers according to the invention, especially in the assessment criterion stickiness and the associated ease of movement, a significant improvement over the species according to Comparative Examples 1 and 2 could be achieved. Furthermore, the copolymers according to the invention provide good stability. It is possible to apply extremely thick layers of plaster, to process them smoothly, without the plaster mixture falling off the wall. This advantage is illustrated especially with the polymeric mixtures 1 and 2. The water retention properties of the copolymers according to the invention are also higher than those of the species according to Comparative Examples 1 and 2. The pleasant and simple processability leads to a significant reduction in the effort required to apply and distribute the fresh gypsum plaster and to simplify the individual work steps. All copolymers show consistently high levels of air pore stability. Of these, in turn, the copolymers 4, 5, 6, 8 and 9 are particularly characterized, which allow a particularly good air-pore stability and thus improved dispersibility of the plaster mixture.
