Abstract
The present invention relates to the preparation of aqueous based polymers bearing reactive functional groups. More particularly, this invention relates to waterborne or water dispersed polymers that are equivalent in performance in applications formerly dominated by solvent based polymers. Polymers of the present invention have many uses including adhesives, saturant applications, solutions or dispersions in water or water-cosolvent mixtures, and are most useful as coatings and sealants for wood, glass, metal, concrete and binders for mortars and non-wovens. More specifically, surface coatings produced from polymers of the present invention exhibit improved properties such as: for example, durability, toughness, solvent resistance, dirt pickup resistance, print and block resistance and mar resistance.
