12. 13C spectra obtained from polymers prepared with 3:1 and 1:1 E:I monomer feed ratios. Further evidence for the proposed assignments is obtained from HMQC and HMBC spectra which are presented below.
13. 13C resonances from atoms which are one- or two-bonds removed. Methylene protons in r diads are essentially chemically equivalent and those in m diads are nonequivalent; therefore carbons which are directly bound to nonequivalent protons are located in m diads. These results are being reported elsewhere.
