Abstract

We have used¹H NMR spectroscopy to study commercial samples of chloro-substituted and bromo-substituted butyl rubbers. We propose calculation formulas for quantitative determination of the main forms in halobutyl rubber (1,4-isoprene, exo form) and its characteristics: unsaturation level, halogen content in the isoprene units. We show that it is possible to determine the main structural characteristics of bromobutyl rubber in the presence of filler.
