Abstract
AbstractHigh resolution nuclear magnetic resonance spectra of a number of a number of samples of poly(vinyl chloride) have been obtained. The methinyl proton spectrum consists of three quintets which have been assigned to isotactic, heterotactic and syndiotactic triads. Determinations of the relative numbers of each triad in several samples of polyvinyl chloride indicate that the degree of stereoregularity is not strongly affected by changes in polymerization solvent or temperature.The various conflicting analyses which have been previously suggested for the polyvinyl chloride methylene proton spectrum are also discussed. The 100 Mc.‐spectrum of poly(α‐deuterovinyl chloride) indicates that the methylene proton spectrum consists of two overlapping triplets from isotactic and syndiotactic diads. The possibility that the methylene proton spectrum is complicated by the presence of branching in poly(vinyl chloride) is also suggested.
