摘要：

Star-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.
