    • Although the thermal or rhodium-catalyzed radical polymerization of N-allenyl-γ-butyrolactam has been reported, the polymer yields were relatively low (up to 30%) and the polymer structures were not fully characterized. See: Leland, J.; Boucher, J.; Anderson, K. J. Polym. Sci., Part A: Polym. Chem. 1977, 15, 2785.

    • The inactivation of the propagating end observed in the postpolymerization experiment might be one of the reasons for a little broader molecular weight distribution of the polymers by 1a.

    • In the case of poly(2a), the GPC method proved to overestimate the molecular weight, while poly(2c) resulted in the considerable underestimation. Although the reason is not clear, we assume that the difference originates from a little different basicity of the amide moieties and the regularity of the double bond geometry of the repeating units (vide infra).

    • 2 under the conditions employed for the kinetic investigation (at 0°C) made it difficult to carry out the quantitative analysis.

    • Similar phenomena have been observed in the ring-opening metathesis polymerization of 3-substituted cyclobutenes and 5-substituted cyclooctenes. See, for example: Maughon, B. R.; Grubbs, R. H. Macromolecules 1997, 30, 3459.
