Abstract
N-chlorolactams, -amides, and -carbamates are photolyzed in alcoholic solution to provide N-(alpha-alkoxyalkyl)-substituted derivatives. These derivatives are interacted with hydroxylated acrylate or methacrylate esters to yield monomers which may be polymerized in the presence of an appropriate initiator. Many of the monomers are water soluble and are useful to prepare polymeric films having unique properties.
