Abstract

Stars with C60 fullerene core and poly (styrene) (PS) arms have been studied in benzene and in the bulk by neutron spin echo (NSE). Behaviours of stars (six arms, each with a mass M = 5 · 103) at momentum transfer q = 0.2-0.6 nm-1 in the time range t = 0.01-20 ns at temperatures T = 20-60°C were compared with dynamics of free PS chains. Displaying depressed molecular mobility, the stars did not obey the usual dynamic Zimm or Rouse model. The fullerene polymer interaction at a specific molecular architecture results in oscillating dynamics.
