Patent

CA 2302336

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.

L'invention porte sur un polymère dont le squelette contenant de l'éthylène présente des substituants lui étant rattachés. Lesdits substituants comprennent une chaîne latérale d'hydrocarbure à liaison azote et couplage uréthane présentant 5 atomes de carbone ou plus en longueur et un groupe méthyle terminal; et un agent solubilisant dans l'eau à couplage oxygène. Ledit polymère, qui s'avère particulièrement utile comme couche anti-adhérence, peut servir à former des pellicules à partir de ses dispersions aqueuses, de ses dispersions dans des solvants organiques, ou de leurs mélanges.
