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.
