Abstract
Molecular hydrodynamics and light scattering measurements have been carried out in dilute solutions of polysilanes copolymers containing segments with different degrees of rotational freedom. For this purpose, three low-molecular-weight linear polydiphenylsilane copolymeric structures containing various amounts of methylhydrosilylene or methylphenylsilylene flexible units have been synthesized and studied. The molecular and hydrodynamic properties of the diphenylsilane copolymers proved to be dependent on their composition and on the chemical structure of the second co-monomer.
