Abstract
An organic polymer including internal pendant phosphorous acid groups at a level of >0.25% phosphorus by weight based on the weight of said organic polymer, the phosphorus acid groups being separated from the backbone of the organic polymer by no more than 2 alkylene glycol units, the organic polymer having an acid number of from 100 to 1,000, and a Mw of from 1,000 to 75,000, wherein the organic polymer has been formed by emulsion polymerization from at least one ethylenically unsaturated monomer is provided. Compositions further including an emulsion polymer including from 0.05% to 2% phosphorous, present as pendant phosphorous acid groups, by weight based on the weight of the emulsion polymer, and, optionally, an inorganic particle are also provided as are processes related to the compositions.
