Abstract Azlactone copolymers having at least two different reactive groups and useful as intermediates for the production of a variety of useful polymeric materials contain repeating units according to the formula (I) ##STR1## wherein R 1 is hydrogen or alkyl (e.g., methyl); each of R 2 and R 3 is hydrogen, alkyl (e.g., methyl, ethyl, propyl, isopropyl); aryl (e.g., phenyl, naphthyl), alkaryl (e.g., tolyl), aralkyl (e.g., benzyl), cycloalkyl (e.g., cyclohexyl, adamantyl), or R 2 and R 3 together with the carbon atom to which they are bonded constitute a carbocyclic or heterocyclic ring; each of R 4 and R 5 is hydrogen or alkyl (e.g., methyl, ethyl); Z is halogen, such as chlorine and each of a and b represents a mole proportion of each of the respective units.
A copolymer containing repeating units according to the formula (I) ##STR16## wherein R 1 is hydrogen or alkyl; each of R 2 and R 3 is hydrogen, alkyl, aryl, alkaryl, aralkyl, cycloalkyl, or R 2 and R 3 together with the carbon atom to which they are bonded constitute a carbocyclic or heterocyclic ring; each of R 4 and R 5 is hydrogen or alkyl; Z is halogen, and each of a and b represents a mole proportion of each of the respective repeating units.
