The Investigation of the Properties of Nitrocellulose Molecules in Solution by Light-Scattering Methods. II. Experimental Results and Intepretations.

Techniques and instruments developed in this laboratory for the determination of the sizes and shapes of high-polymer molecules by the light-scattering method were described in a previous paper (a), which in the following will be referred to as Paper No . I. The present paper describes the application of these methods to a study of a series of nitrocellulose fractions which has resulted in rather definite conclusions regarding the character of the nitrocellulose molecule in solution. The results obtained from the light-scattering measurements are correlated with viscosity and diffusion data by the use of recently developed theories.
