Raman spectra of extended‐chain syndiotactic poly(vinyl chloride)

Abstract: Raman spectra have been obtained for a typical poly(vinyl chloride) (PVC) of low crystallinity and for a highly crystalline sample of syndiotactic PVC obtained by irradiation of a urea‐canal complex. Raman measurements have been made on the three different ordered chain structures possible for ordinary PVC. Extended and folded conformations for the syndiotactic structure and a helical structure for the isotactic molecule obey different selection rules and have different dichroic properties in the infrared and … Show more

“…The first reported Raman spectrum of syndiotactic poly(vinyl chloride) was determined by Koenig and Druesedow in 1969. 1 The observed results in Raman agreed well with previous normal coordinate analysis2 for infrared assignments. Sensitivity of the PVC sam-…”

“…The major feature in this spectrum is the broad profile above 1425 cm −1 , due to the unresolved CH 2 scissoring vibration doublet in PVC, a major material component of the bag. 31 Additional bands in the spectrum in Fig. 2B (a) at ~1040, 1580 and 1600 cm −1 have been attributed to the phthalate plasticizer in PVC blood bags 24 Figure 2B (b) is the spectrum of a blood-filled segment acquired using conventional settings, i.e.…”
