Abstract
Disclosed are certain 2-(4-alkenylphenyl-5-oxazolones useful in the production of polymers containing pendant functional groups obtained by nucleophilic ring-opening addition reactions, the 2-(4-alkenylphenyl)-5-oxazolones having the formula ##STR1## wherein R.sup.1 is hydrogen or alkyl; each of R.sup.2 and R.sup.3 is hydrogen, alkyl, aryl, alkaryl, aralkyl, cycloalkyl, or R.sup.2 and R.sup.3 together with the carbon atom to which they are bonded constitute a carbocyclic or heterocyclic ring.
