Poly(styrene) stars (PS)6C60, twin-cores (PS)6C60-[Si-(CH3)2]-C60(PS)6 and hybrids (PS)6C60(PTBMA)6 with paired arms of PS + poly(tertbutylmethacrylate) have been studied in toluene (20°C, concentration C = 1-6 wt.%) by small-angle neutron scattering (SANS) at momentum transfer q = 0.001-5 nm-1. The C60 stabilize arms' stretched conformation and intensify stars' ordering. While the (PS)6C60 and hybrids formed tiny clusters (particles' number N ∼ 10-80, size RC ∼ 50-100 nm), the dimers created massive structures (N ∼ 1 · 103-2 · 103, RC ∼ 300 nm) that can be induced by dipolar interaction of C60 twin-cores.
