Abstract
The presently claimed invention relates to polymer with branched structure, in particular, hydrophobically modified alkali-soluble (or alkali-swellable) emulsion (HASE) copolymers which are effective thickeners at high shear rates and at the same time offer a Newtonian rheology profile and their use in aqueous compositions, particularly in aqueous coating formulations as well as a method for preparing hydrophobically modified alkali-soluble (or alkali-swellable) emulsion copolymers.
