Ww. Zhao et al., FORMATION OF CONJUGATED DOUBLE-BONDS IN POLY(VINYL ALCOHOL) FILM UNDER IRRADIATION WITH GAMMA-RAYS AT ELEVATED-TEMPERATURE, Chemistry Letters, (2), 1997, pp. 183-184
Irradiation with gamma-rays promotes the formation of conjugated doubl
e bonds in a poly(vinyl alcohol) film at an elevated temperature. The
unsaturation structures resulted by gamma-irradiation were assigned to
be mainly polyenones, -(CH=CH)(n)-CO-, whereas thermal activation pro
duces mainly polyenes, -(CH=CH)(n)-.
