Abstract
Water retention additives for aqueous construction systems including joint compounds are described which are the reaction product of monomers comprising carboxylic acid monomers, nonionic vinyl monomers and specific surfactant monomers. Processes for making such polymers are described as well as the use of aqueous construction systems using the polymers. The polymers are useful in joint compounds and a broad range of similar construction systems as cellulosic replacements.
