Poly(phenylene oxide) was incorporated by small amounts (1, 3, and 5 wt%) of hybrid macromolecular stars with fullerene С60 core and polymer arms of different nature (six nonpolar arms polystyrene and six polar arms of diblock copolymer poly(2-vinyl pyridine)-b-poly(tert-butylmethacrylate). The properties of composite materials were studied in solutions (dynamic light scattering, сapillary viscometry) and in the solid phase (TGA, X-ray diffraction analysis, and dielectric spectroscopy). To characterize physical properties, density and contact angles were determined. Transport properties were studied by measuring the permeability of H2, O2, N2, and CH4 through films containing 0, 1, 3 and 5 wt% hybrid macromolecular stars. An increase of the modifier content in the composite leads to a certain decrease in the permeability coefficients for all gases, but the ideal selectivity in the separation of the O2/N2 and H2/CH4 gas pairs increases.
