Abstract
A composition comprising a polymer, wherein the polymer comprises at least one of: i) a blend of a first polymer comprising a reaction product of acetoacetoxyethyl (meth)acrylate monomer and a second polymer comprising a reaction product of castor oil (meth)acrylate monomer, and ii) a third polymer comprising a reaction product of acetoacetoxyethyl (meth)acrylate monomer and castor oil (meth)acrylate monomer. These polymer compositions can be cured by at least one of auto-oxidation and actinic radiation. Optionally, at least a portion of the acetoacetoxyethyl (meth)acrylate moieties in the polymer can be converted to a corresponding enamine by reaction with at least one of ammonia and an amine.
