Abstract: Supports having azlactone-functional surfaces, adduct supports prepared from such azlactone-functional supports, and methods of preparing both are disclosed. Azlactone functionality is introduced to surfaces of a pre-existing support in a manner which retains useful physical and chemical characteristics of the pre-existing support. One method involves exposing surfaces with high energy radiation to generate free radical reaction sites on the surfaces and causing azlactone-functional moieties to react with the free radical reaction sites. Another method involves coating surfaces with azlactone monomers, crosslinking monomers, and optionally co-monomers and polymerizing the monomers to form a polymerized coating of azlactone-functionality on the surfaces. Another method involves dispersion polymerization of azlactone-functional moieties to produce azlactone-functional particles within pores and interstices of a pre-existing support.
