Abstract: The present invention relates to a water redispersible polymer powder (RDP) which comprises a co-dried admixture of a water-insoluble film forming polymer, a colloidal stabilizer and rubber particles. The presence of rubber within the RDP does not significantly affect redispersibility and may, when incorporated into hydraulically-binding compositions, provide an improvement in the physical properties of the resultant hydraulically bound composition.

Abstract: The present invention relates to a redispersible polymer powder (RDP) composition for use in the preparation of dry mortar formulations, in particular, cement based tile adhesives (CBTA), adhesive, ETICS base coat or adhesive formulations and/or grouts. The invention further relates to a dry mortar formulation comprising said RDP composition. Furthermore, the invention is directed to the use of such RDP compositions for increasing, once cured, the adhesive, flexural and/or compressive strength of a dry mortar formulation.
