✦ Synopsis

The development of biospecific polymeric biomaterials requires new methods of chemical treatment that may be achieved whatever the involved polymeric surface without any degradation of the macromolecular structure. To check whether substitution of polymeric surfaces by epoxy groups could be a suitable way of synthesis to reach this goal, functionalization of polystyrene by epoxy groups was carried out. The respective reactions of carboxylic acids, alcohols, aldehydes, hydrochloric and sulfuric acid, and benzylamines have been extensively studied and suitable characterization has been performed on the respective polystyrene derivatives using infrared spectroscopy, elemental analysis, argentimetric titration, and acidimetric titration. In addition, a method of titration of the epoxy groups' content of insoluble functionalized polymers has been developed by the use of I4C-labeled benzylamine.
