Description
Summary:Observation of the infrared spectra of vinylidene chloride and vinyl chloride copolymers permitted clarification of some points which were rather ambiguous from the study of the homopolymers, and gave some information on the bands of the copolymers. In particular, the band at 868 cm.−1, which had been considered to be that of polyvinylidene chloride, was observed only in the copolymer. Depending on the mode of arrangement of vinylidene chloride and vinyl chloride in the copolymer, the CH‐deformation frequency appears at 1206, 1245, or 1255 cm.−1. The same behavior was observed with vinylidene chloride‐vinyl bromide copolymers. With the copolymer rich in vinylidene chloride, the band at 1206 cm.−1 can be used for determination of vinyl chloride content. In deuterated vinylidene chloride‐vinyl chloride copolymer, the CD2‐bending frequency due to the CDClCD2CCl2sequence appears at 1081 cm.−1.
