A low molecular weight copolymer reaction product of a copolymer acid of an .alpha.-olefin and an unsaturated carboxylic ac- id, preferably an .alpha.,.beta.-ethylenically unsaturated carboxylic acid, and at least one amino acid compound. The present invention in- cludes a method of preparing the copolymer reaction product. The reaction product has excellent compatibility with other polym- ers, particularly polyamides. The copolymer reaction product is useful in a method to flush water from pigments. |
