| abstract |
The invention relates to a liquid dispersant based on polyamine-graft-polyacrylate blend, its preparation and its use in solvent borne systems, especially to a polyamine-g-polyacrylate grafted copolymer blend of the general formula (1) ora mixture of formula (1) and Y T-(A1,A2)-Y1 wherein T is a polyamine or polyimine, A1 is a bridging bond which is selected from amide or imide, A2 is a -N-C- bridging bond, Y is an acrylate residue of the general formula (2), wherein, R1and 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 average molecular weight of 50 000g/mol to 150 000 g/mol and a polydispersity Mw/Mn is greater than 3. |
