A mixture of vinyl acetate, water and polyoxyethylene nonyl phenyl ether sodium sulfate (LWZ; Kao Co.) was irradiated with a high pressure mercury lamp in the absence of initiator at 0°C and high molecular weight poly(vinyl acetate) (PVAc) which gave poly(vinyl alcohol) (PVA) of Pn (average degree of polymerization)=12800 after hydrolysis was obtained in good yield. Initiation by a radical from LWZ decomposed by photoirradiation was deduced. The charateristics of the PVA were similar to those of usual PVA. |
