Abstract
The present invention relates to an oligomer with a semi-telechelic nitrogen-functionality and at least one ethylenic unsaturation pendant to the backbone of the oligomer. In addition, a process is provided to prepare the semi-telechelic nitrogen-functional oligomer. The semi-telechelic nitrogen-functional oligomer is useful as a dispersant for pigments in radiation curable formulations.
