    • Although both 35DMPNO and HMPA are Lewis bases, different stereospecificities were induced. We have proposed that the stereospecificity induced with Lewis bases depended on the structure of the hydrogen bonding-assisted complexes between NIPAAm and the added Lewis bases. Formation of 2:1 complex between NIPAAm and PNO derivatives would be the key for isotactic-specific polymerization [16b], whereas formation of 1:1 complex between NIPAAm and HMPA would be required for syndiotactic-specific polymerization [14b].

    • 2 [30] was found in 35DMPNO used in the present study. These results suggest that polymerization in the presence of 35DMPNO does not proceed in a living manner.

    • note
    • 13C NMR spectrum of poly(NMAAm) exhibited no clear splitting due to triad tacticity. Therefore, we discussed stereoregularity at dyad level in this paper.
