Based on the results of rapid-flow electron spin resonance (RF-ESR) and spin-trapping (ST-ESR) measurements, carbonyl-conjugated radicals derived from the vicinal diol moiety (2, i.e., the head-to-head structure) of poly(vinyl alcohol) (PVA) have bee

Continuous rapid-flow electron spin resonance (ESR) was used to detect poly(vinyl alcohol) (PVA)-derived carbon-centered radicals, in order to characterize the short-lived intermediate radicals in the initial stage of the graft polymerization of PVA.

Autor: Yoichiro Saito, Keiichi Kuboyama, Yuko Nishihara, Yoshinori Kobayashi, Koichi Hirata, Makoto Muramatsu, Toshiaki Ougizawa, Kenji Ito, Masayuki Okura, Tomoyuki Yamamoto

Publikováno v: Radiation Physics and Chemistry. 68:561-564

Relationship between oxygen permeability and free volume hole size evaluated from ortho -positronium lifetime in ethylene–vinyl alcohol copolymer (EVOH) was studied as functions of temperature and relative humidity. As the relative humidity rises a

Spin Trapping Chemistry of the Diphenylphosphinyl Radical

Autor: Yuko Nishihara, Yoshimi Sueishi

Publikováno v: Journal of Chemical Research. 2001:84-86

The diphenylphosphinyl radical (·PPh2), produced from hydrogen atom abstraction of diphenylphosphine by 2,2-diphenyl-1-picryl-hydrazyl, was trapped by several kinds of spin trap and the relative reactivities of the ·PPh2 radical toward the five kin
