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