Abstract: The presently claimed invention relates to an amine-modified polymer and method for preparation thereof. The presently claimed invention is also directed to the use of the polymer as dispersant in ink and coating compositions. Polyacrylate polymer is obtained by controlled free radical polymerization of a mixture comprising at least one acrylate monomer. The post-modification of polyacrylate polymers yields amine-modified polymers that provide improved viscosity parameters, without sacrificing the advantages of a well-defined polymer structure.

Abstract: The presently claimed invention is directed to a copolymer obtained by reacting at least one isocyanate (A) comprising at least one allophanate group and at least one active double bond with at least one isocyanate reactive component (B) to form an intermediate product (C); and reacting the intermediate product (C) with at least one active double bond reactive component (D) to obtain the copolymer which can be used as dispersant. The at least one isocyanate reactive component (B) is selected from the group consisting of monofunctional polyether amine (B1), monofunctional polyether alcohol (B2), C6-C30 monofunctional alcohol (B3) and monofunctional polyester alcohol (B4).
