Abstract

A polymer includes an ethylene-containing backbone having substituents attached thereto, wherein the substituents include a urethane linked nitrogen-bonded hydrocarbon side chain having about 5 carbon atoms or more in length and a terminal methyl group; and an oxygen linked water solubilizing group. The polymer is particularly useful in a release coating composition and is suitable for forming films from aqueous dispersions thereof, organic solvent dispersions thereof, or mixtures thereof.
