Abstract:
A reaction product of: (i) an oligomer formed from one monomer or two or more different monomers, the or each monomer being an ethylenically unsaturated compound, said oligomer or each of said monomers being optionally partially or fully esterified, wherein the oligomer formed is selected from the group consisting of styrene copolymerized with maleic anhydride, styrene copolymerized with acrylic acid and polyacrylic acid, with (ii) a polyalkenyl derivative of (iii) an ethylenically unsaturated carboxylic reagent selected from the group consisting of monoethylenically unsaturated C.sub.4 -C.sub.10 dicarboxylic acids and anhydrides, and (iv) a polyamine containing at least two groups selected from the group consisting of --NH.sub.2, --NH and mixtures thereof, wherein at least one of the ethylenically unsaturated compounds of the oligomer has a functional group which can react with an amine.
