Patent abstract

Crosslinked polymeric materials are described that contain pendant amine capture groups. The amine capture groups include N-sulfonyldicarboximide groups that can react with amine-containing materials by a ring opening reaction. Reaction mixtures used to prepare the crosslinked polymeric materials, articles containing the crosslinked polymeric materials, methods of making articles, and methods of immobilizing an amine-containing material are also described.
