Polymeric dispersants containing one or two quaternary amine anchoring groups with improved chemical and thermal stability
The present invention relates to a dispersant having a tertiary or quaternary amine anchoring group and a solubilizing polymer selected from C.sub.8-50 fatty acid; a C.sub.8-50 ak(en)yl substituted succinic acid, anhydride or partial ester; a dimer or trimer fatty acid; and/or polymers from repeating units of polyesters, polyethers, polyacrylate, polyamides, polyurethanes or mixtures of said repeating units in a random or blocky copolymer. The dispersants are an improvement in that the alkylene connecting group between the tertiary or quaternized amine and the solubilizing polymer lacks abstractable hydrogen atoms at the geminal carbon atom from the nitrogen of the tertiary or quaternized amine over the prior art. The dispersants are useful as dispersants with improved thermal stability and low amounts yellow color after aging at elevated temperatures.
