Synthesis of hybrid fullerene-containing polymers with the controlled molecular mass characteristics of polymer fragments

Star-shaped fullerene-containing polymers were synthesized by the reactions of nucleophilic addition of active poly(ethylene oxides) and living polyst yrenes to C-60 fullerene. The resulting polymers were used to prepare new h ybrid star-shaped polymers with C-60 fullerene as a core and poly(ethylene oxide) and poly(tert-butyl acrylate) as arms, as well as the hybrid polymer s of complex architecture based on poly(vinylpyrrolidone) onto which the st ar-shaped fullerene-containing poly(styrenes) were grafted. Poly(acrylate) fragments involved in star-shaped hybrid polymers were subjected to hydroly sis. The reaction of fullerene, which was preliminarily activated with pota ssium tert-butoxide, with the carbonyl groups of poly(vinylpyrrolidone) yie lded an irregular network polymer. The products were analyzed by HPLC, and the analysis data support formation of hybrid polymers.
