ABSTRACT:
A graft copolymer having a polymeric backbone with pendent hydroxyl groups; wherein the hydrogen atom of at least the one the hydroxyl groups is replaced by the formula ##STR1## where R is an aliphatic group, a cycloaliphatic group or an aromatic group; R.sup.1 is an alkylene group having 2-6 carbon atoms; R.sup.2 is a polymer segment of a vinyl addition polymer, such as butyl acrylate/hydroxyethyl acrylate; coating compositions of this copolymer can be cross-linked with conventional cross-linking agents such as an alkylated melamine formaldehyde resin or an organic polyisocyanate and coating compositions useful for flexible elastomeric substrates can be prepared from this copolymer.
