Abstract: Deuterated star-shaped polystyrenes, (PS)6C60, dissolved in protonated analogs (1; 10% mas.), have been studied (20°C) by small-angle neutron scattering as compared to linear chains with arm's mass MA ∼ 5∙103. Using correlation functions of chain units in stars regarding to linear PS, we have developed a model of star where the arms' centers lay on the orthogonal axes, whose origin is attached to fullerene. Neutron scattering data detected more stretched arms' conformation in stars than for linear chains. [ABSTRACT FROM AUTHOR]
