ABSTRACT:
This invention presents a series of polyfunctional polymers useful as deinking agents. The polymers, which generally have molecular weights in the 2,000-100,000 range, can be used to effectively separate and remove ink in a variety of deinking processes, including flotation, wash, and mechanical, resulting in fibers of superior brightness.
