Synthesis and bioimmunological efficiency of poly(2-oxazolines) containing a free amino group

Novel amphiphilic copolymers on the basis of 2-oxazolines containing a free amino group were prepared. The copolymers were synthesized by the living cationic polymerization of 2-ethyl-2-oxazoline (ETOX) and 2-(4-aminophenyl)-2-oxazoline (APOX). The main goal of this work was the synthesis of water soluble polymer material with the defined number of functional groups necessary for the attachment of proteins and polysaccharides. A high concentration of free amino groups allows immobilization of various biosubstances, e.g. drugs, proteins or polysaccharides. Thermal properties have been studied with respect to the composition of the copolymers. Cytotoxicity and the bioimmunological efficiency of the selected copolymer were studied.
