MOLECULAR-WEIGHT CHANGES DURING AUTOXIDATION OF ATACTIC POLYPROPYLENE IN SOLUTION.

Abstract

Expressions previously reported for changes in intrinsic viscosity as a function of time during the autoxidation of atactic polybutene-1 in the bulk phase were applied to the data provided by Bawn and Chaudhri for the autoxidation of atactic polypropylene in solution. The quantitative evidence obtained indicates that the intrinsic viscosity relationships which were found to be valid for the autoxidation of APB in the bulk phase are also valid for the autoxidation of APP in solution (at polymer concentrations of ca. 1.5 M and above).
