摘要：The invention relates to a liquid dispersant based on polyamine-graft-polyacrylate blend, its preparation and its use in solvent borne systems, especially to apolyamine-g-polyacrylate grafted copolymer blend of the general formula (1) or amixture of formula (1) and YT-(A1,A2)-Y1 wherein T is a polyamine or polyimine, A1 is abridging bond which is selected from amide or amide, A2 is a —N—C— bridging bond, Y isan acrylate residue of the general formula (2), wherein, R1 and R2 are, independently,hydrogen or C1-20alkyl, aryl, heteroaryl, substituted aryl. n is a number of 1-1000,wherein the polyamine-g-polyacrylate grafted copolymer blend has an averagemolecular weight of 50 000 g/mol to 150 000 g/mol and a polydispersity Mw/Mn isgreater than 3.
