Abstract

AbstractA review of reactive carriers and immobilized enzymes describing the latest developments in the authors' laboratories is presented. Slightly basic and amphoteric reactive carriers were synthesized on the basis of poly (ethylene imine), and neutral hydrophilic carriers were obtained on the basis of polyethers. A new possibility for the Ugi reaction including carbon dioxide as the fifth component in this reaction is shown. Crosslinked acrylic acid–styrene copolymers and also poly(vinyl alcohol) were used for the introduction of maleimide groups, giving polymers with a specific reactivity towards SH‐groups containing enzymes resp. thiolated enzymes. A poly(vinyl alcohol) containing fiber material, synthetic pulp, was modified with diazonium groups and used for the immobilization of different enzymes. The properties of the immobilized enzymes were investigated.
