1. 1. Porous Polymeric Monoliths by Less Common Pathways : Preparation and Characterization

   Författare :Ahmed Elhaj; Knut Irgum; Sebastiaan Eeltink; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Monolith; commodity polymer; thermally induced phase separation; dissolution-precipitation; polymer solvents; porogenic polymer; step-growth polymerization; separation science; melamine-formaldehyde;

   Sammanfattning : This thesis focuses on my endeavors to prepare new porous polymeric monoliths that are viable to use as supports in flow-through processes. Polymer monoliths of various porous properties and different chemical properties have been prepared utilizing the thermally induced phase separation (TIPS) phenomenon and step-growth polymerization reactions.
