32. Acetic acid was added to quench the reaction. See ref 11a.
33. 3: δ 126.70, 127.58, 127.80, 131.79, 139.36, 142.90. These values are in good agreement with those reported for cis-transoidal PPA. See refs 10b, 10e, 10g, and 11.
34. total is the total area of the spectrum. However, this procedure does not allow for exact assignment of the stereochemistry of PPA, which has to await further elucidation. Therefore, the resulting value is used here only as a qualitative measure for stereoregularity without direct implications on the exact structure. We gratefully acknowledge helpful comments on stereochemical analysis of PPA by one of the referees.
35. -1 supports that this insoluble species is mainly cis-cisoidal PPA. See: Simionescu, C. I.; Percec, V.; Dumitrescu, S. J. Polym. Sci., Polym. Chem. 1977, 15, 2497-2509 and refs 10e and 10h.
36. The SEM image of the THF-insoluble part showed a much more compact structure than that of the THF-soluble part. This is consistent with the insolubility and the cross-packed structure of cis-cisoidal PPA.
