| Research Abstract |
Stereospecificities were successfully induced not only in radical polymerization but also in anionic polymerization, with the aid of formation of hydrogen-bond-assisted complexes of amide-containing monomers, such as N-allyl-N-tert-butylacrylamide, N-vinyl-2-pyrrolidone, N-n-propyl-alpha-fluoroacrylamide, and N-isopropylacrylamide. In particular, chirality was also induced in the polymerization of N-allyl-N-tert-butylacrylamide in the presence of chiral tartrates.
Statistical 2D NMR, in which principle component analysis was applied, successfully interpreted assignments of NMR spectra of synthetic polymers in terms of stereoregularities. In addition, tacticities distributions were precisely predicted by partial least squares regression.
