The number of internal double bonds in poly(vinyl chloride) (PVC) samples was studied as a function of molecular weight at various monomer conversions. These defect structures were found to exhibit end-group-like characteristics: their concentration per chain was largely constant as a function of molecular weight. This tendency was independent of the degree of conversion. An intramolecular mechanism for formation of unsaturated structures and their location between carbons 5-6 were confirmed...[Show more]
