Synthesis and properties of macromolecular esters of carboxy-substituted derivatives of hindered phenols

Macromolecular esters were synthesized from carboxy-substituted derivatives of spatially hindered phenols and hydrophilic polymers: dextran, hydroxyethylated starch, poly(ethylene glycols) of various molecular weight. The hybrid macromolecular antioxidants significantly surpass in antiradical and an...

Description
Summary:Macromolecular esters were synthesized from carboxy-substituted derivatives of spatially hindered phenols and hydrophilic polymers: dextran, hydroxyethylated starch, poly(ethylene glycols) of various molecular weight. The hybrid macromolecular antioxidants significantly surpass in antiradical and antioxidant activity the low molecular weight analogs of the hindered phenols. This is indicative of the changed mechanism of the redox-processes in water and of the governing role therein of the supramolecular hydrated structures formed by the solvation of polymer molecules in water environment.
