Conformational properties of the molecules of ethylphenyl(diphenyl)sil
oxane copolymer in benzene were studied by methods of flow birefringen
ce, viscometry, and translational diffusion. The high content of pheny
l side groups and their interactions are the factors determining on th
e molecular level the conformational features of the copolymer, includ
ing high equilibrium rigidity and large optical anisotropy of the mole
cules.
