It was shown by light scattering that cellulose tributyrate (CTB) molecules have increased rigidity. The size of the Kuhn segment reaches 200 Å in methylethyl ketone and 140 Å in bromoform. The conformation of CTB molecules in solution in the range of molecular weights studied corresponds to the conformation of a Gaussian sphere, which is characterized by the flow effect caused by a considerable equilibrium rigidity of the macromolecular chain of CTB. Molecular chain diameters of CTB calculated from experimental results are correlated with values obtained previously from hydrodynamic results. © 1977.
