Notes:
In the presence of Et2SO4, (S)-1-(N-phenyl-carbamoyl)-2-methylaziridine gave an oligomer with a structure of [CH2—CHCH3—N(CONHPh)]n. The oligomer has optically active isotactic configuration and narrow molecular weight distribution (DP ca. 8). The net polymerization behavior of the monomer and chemical property, such as absorptivity of Et2SO4, of the oligomer are analogous to the case of 1-(N-phenyl-carbamoyl)-aziridine. The ring opening occurs with retention of the configuration at the asymmetric carbon atom and the oligomer can be crystallized at around 90°C.
