(meth) acrylic polymers non-water soluble amphibious combs. The invention consists of non-water soluble polymers with comb structure having a (meth) acrylic backbone over which side chains containing at least one hydrophobic monomer of the styrene or (meth) acrylic ester type in c1 to c4 and at least a hydroxy or methoxy polyalkylene glycol monomer. the monomer contents are such that said polymer is amphiphilic because it is rich in both hydrophobic monomer and polyalkylene glycol monomer. These products, used in paper coating pastes, increase brookfield ^ tm ^ viscosity, decrease acav viscosity and improve water retention, making them particularly well suited for coatings with dry extract content and / or speed. high deposition levels.
