Abstract: The relation of concn. to viscosity in solns. of pure poly(vinyl chloride) PCU-G (Buna-Werke, Schkopau) (I) in cyclohexanone at temps. of 15°, 40°, 63.5°, and 84° and concns. of 0.2-1.5 g./100 ml. was studied. The kinetic correction and the correction for the gravity were applied. The relation found does not correspond to the values expected from Fikentscher's equation (C.A. 26, 5414) and k values so derived depend on concn. and temp. Hence, Fikentscher's equation is not recommended for evaluation of a mol. wt. of polymer in I.
