ABSTRACT:
Azlactone-functional polymer beads are useful reactive supports for the attachment of functional materials to provide novel adduct beads. The adduct beads are useful as complexing agents, catalysts, reagents, and as enzyme or other protein-bearing supports. Novel carboxylate-functional polymer beads, are intermediates in the preparation of the azlactone-functional beads.
Azlactone-functional beads have units of the formula: ##STR1## wherein R.sup.1 is H or CH.sub.3,
