摘要

The present invention relates to a comb-like polymer characterized by a (meth) acrylic skeleton having a side chain of the hydroxy or alkoxy polyalkylene glycol type and entering into the composition of a paper coating dispersion. They cause retention of water retention and viscosity under low shear gradients and considerably reduce the viscosity under high stresses, thereby canceling the phenomenon of increasing blade pressure, which results in increased drying and / . / RTI The invention also relates to the coating dispersions thus formulated and their application to the surface of paper sheets.
