Science, 7, Part A-1, pp. 3151-3158, 1970-02-01 Thermal decomposition products of poly(vinyl alcohol) Tsuchiya, Y.; Sumi, K. Journal of Polymer SynopsisThe thermal decomposition of poly(viny1 alcohol) is known to occur in two stages. In a study of firststage decomposition, this polymer was pyrolyzed in vacuum at 240°C for 4 hr and the products were determined by using gas chromatography. The main products were water, aldehydes having the general formula HC+CH=CII-fCI-13, and I I n 0 methyl ketones having the formula RJC-C+CH=CH-fCI-13, where n = 0, 1, 2, 3, etc.
