Experimental results on the study of electro-optical, dielectric and hydrodynamic solution properties of 6-arm polystyrene stars A6C60(PS)6 with a variable structure of low molecular addend, A, are reported. Strong dielectric polarization of A6C60(PS)6 have been detected in external electric fields of radio frequency range and explained by intermolecular long lifetime charge-separated state of highly symmetric fullere adducts situated at the central part of polystyrene stars.
