Abstract
AbstractThe reaction of chlorine or nitrogen dioxide with polybutadiene consists mainly in their addition to the double bonds of the polymer, but it is often followed by a number of secondary reactions, such as crosslinking and cis‐trans isomerization. The addition reaction of nitrogen dioxide is always accompanied by cyclisation.The cis‐trans isomerization, the effect of the solvent nature and catalyst, and the CCl trans‐gauche configuration in the reaction with chlorine were studied by IR spectroscopy.The cis‐trans isomerization, the degree of cyclisation, and the proportion of crosslinked double bonds, in the reaction of nitrogen dioxide were also studied by IR spectroscopy.
