Notes:
From the temperature dependence of infrared spectra of poly(vinyl chloride) samples prepared by different methods, the intensity of the band at 690 cm.1 (proportional to the number of isotactic diads in the sample), as well as that of the tacticity-independent C—H stretching band, was found to be independent of the crystallinity of the sample. These lines were therefore applied for the tacticity determination in poly(vinyl chloride), measured in the form of KBr pellets. The numerical tacticity value was obtained from the known values of absorbance coefficients of SCH and SHH type C—Cl stretching bands in solution, and from the shape of the spectrum.
