Abstract
The hyperbranched copolymers of tris(pentafluorophenyl)germane (C6F5)3GeH and bis(pentafluorophenyl)germane (C6F5)2GeH2, synthesized by the method of activated copolycondensation, have been studied by means of dynamic and static light scattering methods, analytical ultracentrifugation, isothermal translational diffusion, and capillary viscometry in dilute chloroform solutions. It has been shown that the copolymer molar mass grows with increasing content of (C6F5)2GeH2. The molecules of polymer investigated have a compact dense structure, their shape being slightly different from the spherical one.
