Abstract
A number of low‐conversion unfractionated polymers of acrylonitrile have been prepared by polymerization of the monomer alone and in solution in dimethylformamide. Number‐average molecular weights (28,000 to 1,000,000) were determined by osmometry and intrinsic viscosities measured in dimethylformamide at 25°C. The equation: was obeyed within the limits of experimental error over the whole range. This relation is derived from one previously obtained by Cleland and Stockmayer from light‐scattering measurements on low‐conversion transfer polymer.Keywords
