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.sup.1 is hydrogen or alkyl (e.g., methyl); each of R.sup.2 and R.sup.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.sup.2 and R.sup.3 together with the carbon atom to which they are bonded constitute a carbocyclic or heterocyclic ring; each of R.sup.4 and R.sup.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.
