| Abstract: | The hydrodynamic and conformational properties of silicon-containing polynorbornene prepared by metathesis polymerization of 5-trimethylsilylnorbornene in the presence of Grubbs Ru carbene complex were studied by viscometry, isothermal translation diffusion, and centrifugal sedimentation. For the ten-sample homologous series of the polymer, Mark-Kuhn-Houwink relationships correlating the hydrodynamic characteristics of the molecules in toluene with their molecular weight were obtained.
