Abstract: The presently claimed invention provides a continuous process for preparing a polyurethane composition which behaves as a rheology modifier upon addition to paint and coating formulations. The present process employs mixers for homogenization of highly viscous polyurethane polymers and by adjusting the process parameters and reactor conditions in specified ranges obtained a polyurethane composition. The polyurethane composition obtained from the process of the present invention is used as thickener in water-borne paint and coating formulations.

Abstract: The present invention relates to a process for the preparation of a polymer composition comprising at least one polymer and at least one polyether compound (PE), The polymer is obtained by radical polymerization of a monomer composition (M) comprising at least one olefinically unsaturated acid monomer and optionally further monomers such as a chain transfer agent. The radical polymerization is carried out in at least one continuously operated back-mixed reactor and in the presence of the polyether compound (PE).
