Abstract:
The present invention concerns aqueous polymer compositions comprising a water soluble hydrophilic polymer with poly(ethylene oxide) content higher than 50% by weight and a polyacrylic thickener containing sulfonic groups. The aqueous polymer compositions of the invention are useful as deflocculants, rheology modifiers and water retention agents for paper coating compositions.
