Abstract

Stars of Poly(styrene) chains grafted to C60 have been studied by SANS and NSE below glass transition (TG ∼ 94°C). In stars the arms are not condensed at fullerene surface, spreading away from C60-core. The interaction between fullerene core and polymer chains slows down the β-relaxation in arms at T = - 20 to + 70°C <TG, so their relaxation time achieves of 10-60 μs (an order of magnitude higher than in free PS-chains). Together with slow processes in stars and PS we also observed a fast oscillation (periods ∼ 1 ns) of correlation function (δ-relaxation). The dynamic model for these stretched oscillations is proposed.
