Abstract
Polymeric urethane dispersants with solubilizing polymer chains and with reactive carbon to carbon double bonds are described. The reactive double bonds facilitate molecular weight build-up of the dispersant on dispersed particles (enhancing colloidal stability) or enhance the ability of the dispersants to be crosslinked into a matrix material.
