Abstract

Configurational analyses of polyacrylonitrile polymerized with manganese(III) diacetylacetonate rhodanide at higher temperature have been made. The Bernoullian probability for meso addition on the monomer units in the polymer chain is 0.5237 from methine and 0.539, from nitrile 13C atoms, and the corresponding average number lengths of the meso sequences are 2.196 and 2.1. The results are similar to those for polymers produced in a free radical process. They show that polymers are atactic and that the mecanism of polymerisation, under these conditions, is radical.
