Popis:	Cellulose myristate samples with a degree of substitution of 230–250 have been studied by the methods of molecular hydrodynamics (viscometry, analytical ultracentrifugation (flotation), and isothermal translational diffusion) in chloroform in the range M = (56–652) × 103. The experimental evidence has been interpreted within the framework of the generalized wormlike Yamakawa-Fuji model with the following parameters: the persistence length a = 115 × 10−8 cm, the chain diameter d = 45 × 10−8 cm, and the molecular mass per unit chain length M L = 270 × 108 cm−1. It has been inferred that the polymer dissolves in chloroform in the form of dimers.
