Abstract
The present invention provides a dramatically improved process for the preparation of acrylamide and methacrylamide functional monomers, oligomers, and polymers that avoids the use of acidic catalysts which can cause undesired side reactions. The present invention process involves reacting an alkenyl azlactone with a hydroxy functional compound in the presence of a catalytic amount of either a bicyclic amidine or a trivalent phosphorus compound. These efficient basic catalysts provide unexpectedly increased reaction rates under mild conditions.
