Abstract
AbstractTwo series of nucleophilic substitution reactions on PVC using either the same nucleophile but different experimental conditions or various nucleophiles in cyclohexanone (CH) dilute solutions, were performed. The evolution of unreacted iso‐, hetero‐and syndiotactic triads with degree of conversion was followed by 13 C NMR. While the kinetics and yield changed markedly with both the type of nucleophile and the reaction conditions the stereochemical structure of modified polymers proved to depend only on degree of substitution. These results afford further support to a conformational mechanism of substitution, as proposed by earlier works.
