Organic and Polymer Synthesis

Organic and Polymer Synthesis (Mark Hempenius)

Mark Hempenius is active in the area of organic and polymer chemistry. Research topics include organometallic polymers, stimuli-responsive polymers, stimuli-responsive surface-anchored polymers, polymer architectures (block copolymers, networks), and functionalized polymers for CO2 capture. These polymers are obtained by living anionic polymerization, controlled radical polymerization methods, and step-growth processes. Organic chemistry and silane chemistry are key competencies required for monomer and initiator synthesis, polymer modification, and the functionalization of surfaces with responsive groups or polymer chains.
