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.
