New rheology modifiers for modifying the rheological behaviour of coating compositions

摘要

The present invention relates to rheology modifiers, which are water-soluble polymers having a weight average molecular weight (Mw) of at least 1000000 g/mol and an intrinsic viscosity of at least 2.5 dl/g, both as determined by size exclusion chromatography, and wherein the water- soluble polymers are in the form of soled particles.
