Branched copolymers dextran-g- polyacrylamide (D-g-PAA) were synthesized using radical graft polymerization method with Ce(IV) as initiator. It was shown that dextran keeps the compact coil conformation during synthesis process. It allowed to synthesize the copolymers corresponded to the theoretical model of spherical brushes. The theoretical predictions about polymer higher compactness of branched polymer systems in comparison with their linear analogues were confirmed. The effect of the internal polymer structure on the hydrolysis process was established. The application prospects for branched polymers Д-g-PAA as matrices in nanotechnology were shown.
