Abstract

Hydrodynamic properties of 10 samples of poly(1-trimethylsilylpropyne) of various molecular weights, obtained with NbCl5 catalyst and containing 60-70% cis C = C bonds, were studied by sedimentation, translation diffusion, and viscometry techniques. The equilibrium rigidity of the polymer molecules was estimated from the viscometric data using the formalism of the intrinsic viscosity theory as applied to the worm-like coil model with excluded-volume effects. For the polymer macromolecules, the Kuhn segment length, thermodynamic parameter ε, and hydrodynamic diameter of the chain d were estimated.
