Abstract

Modified ethylene/n-butyl acrylate copolymers obtained by grafting a half-ester of maleic acid onto a randomly copolymerized ethylene/n-butyl acrylate backbone are provided. The carboxylic functionalized polymers of the invention exhibit superior adhesion to non-polar substrates. They are particularly effective for adhering metals.
