Acrylic polymers.

摘要

The invention relates to acrylic polymers having pendent tertiary alkyl primary amine groups. One embodiment relates to such polymers which have at least one other pendent functionality reactive with isocyanate groups. Another embodiment relates to primary amine group containing copolymerisable vinyl monomer and at least one copolymerisable ethylenically unsaturated monomer characterised as free of primary amine groups. Another embodiment relates to a pigment dispersion composition comprising: (a) from about 1 to about 50 percent by weight of an acrylic polymer having pendent tertiary alkyl primary amine groups as a dispersant; (b) from about 10 to about 90 percent by weight of a pigment; and (c) the balance of a liquid carrier. m
