Notes:
The stereoregularity of polymethacrylonitrile was determined by examining the infrared and NMR spectra of poly(methyl methacrylate) derived from polymethacrylonitrile. Methacrylonitrile was polymerized by n-butyllithium, azobisisobutyronitrile, benzoyl peroxide, and γ-ray irradiation. The J values of the derived poly(methyl methacrylate) are in a range of 56-59, indicating a stereoblock structure. The NMR spectra of the derived poly(methyl methacrylate) showed that the polymers are composed mainly of isotactic-heterotactic structures.
