Notes:
The high resolution NMR spectra of poly(vinyl ethyl, isopropyl, isobutyl, and tert-butyl ethers), yields, upon examination at 60 and 100 Mcycles/sec., and under the conditions of decoupling, information concerning the various tactic forms present. The spectra are complicated by the number of overlapping resonances to the extent that an unambiguous assignment of the three triad forms could not be made. For poly(vinyl isobutyl ether) the resonances of the α proton decoupled from the β protons exhibits three components which are tentatively assigned to the central monomer units in heterotactic, isotactic, and syndiotactic configurations, with increasing field strength, respectively.
