摘要：
A new synthesis of the covalently bound conjugates of dextran and a sterically hindered phenol has been described. Some features of the synthetic procedure have been discussed. The conjugates were investigated as polymeric forms of antioxidants and their radical scavenging activity was studied in the reaction with diphenylpicrylhydrazyl. It was found that the radical scavenging activity of the conjugates was about three times higher in comparison with that of the mixture of a sterically hindered phenol and dextran.
