Abstract
Abstract Polyethylene glycol (PEG) was used as a carrier polymer for the attachment, via end groups, of drugs such as penicillin V, aspirin, amphetamine, quinidine and atropine. For this purpose, methods were developed for the functionalization of PEG; PEG-NH 2 , PEG-COOH and PEG-NCO were prepared. Use was made of dicyclohexyl carbodiimide together with 4-dimethylamino pyridine or 1-hydroxybenzotriazole for the coupling reactions.
