    Abstract: A process for preparing a polyoxazoline includes feeding continuously an oxazoline, a solvent, and a catalyst to a continuous stirred tank reactor at a rate which provides for a residence time sufficient to achieve ring opening of the oxazoline and polymerize the oxazoline; exiting a polyoxazoline solution from the continuous stirred reactor, the polyoxazoline solution including polyoxazoline, solvent, and, optionally, unreacted oxazoline, low molecular weight oligomeric oxazoline, or a mixture thereof; removing the solvent, and, optionally, unreacted oxazoline, low molecular weight oligomeric oxazoline, or a mixture thereof from the polyoxazoline solution; and recovering the polyoxazoline.

    Abstract: Disclosed are functional polyallophanate oligomers comprising ethylenically unsaturated groups and polymer stabilizer groups selected from hindered amine light stabilizers, ultraviolet light absorbers, antioxidants and dihydrocarbylhydroxylamines. The ethylenically unsaturated groups and the polymer stabilizer groups are bound to the polyallophanate oligomers through allophanate and/or carbamate groups. The polyallophanate oligomers are useful in curable coatings, inks and varnishes. The present polyallophanate oligomers are derived from a) organic polyisocyanates, b) compounds containing at least one isocyanate reactive group and at least one ethylenically unsaturated group and c) polymer stabilizers containing at least one isocyanate reactive group.
