The ionomer salt of low molecular weight copolymer reaction product of a copolymer acid of an α-olefin and an unsaturated carboxylic acid, and at least one amino acid compound, and a cation containing material. The unsaturated carboxylic acid is preferably an α,β-ethylenically unsaturated carboxylic acid. The present invention includes a method of preparing the ionomer. The ionomer has excellent compatibility with other polymers, particularly polyamides. The ionomer is useful in a method to flush water from pigments.
