Abstract
SummaryStar‐like dextran‐graft‐(polyacrylamide‐co‐polyacrylic acid) (D‐g‐(PAA‐co‐PAAc) copolymers in a salt form were obtained by alkaline hydrolysis of Dextran‐graft‐Polyacrylamide (D‐g‐PAA) samples. The internal structure of D‐g‐PAA in solution predetermined the reaction course and the conversion degree depended upon the initial architecture of macromolecules. It was shown that macromolecules of D‐g‐(PAA‐co‐PAAc) acquired extended conformation because grafted chains became greatly straightened when charged functional groups appeared. No polyelectrolyte effect for synthesized D‐g‐(PAA‐co‐PAAc) samples was registered. Star‐like polyelectrolytes were proved to be more efficient matrices in comparison with linear anionic Polyacrylamide for silver nanoparticle in situ synthesis.
