Stereoregularity of polymethacrylonitrile
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...

| Zusammenfassung: | 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. |
