Abstract
Two procedures were suggested for separate determination of butyral and furfural acetal groups in polyvinyl butyral furfural acetal copolymer. The first procedure involves chromatographic determination of the volatile aldehydes after preliminary hydrolysis of the copolymer, in combination with chemical determination of the sum of acetal groups in the copolymer by oximation. The second procedure is based on NMR spectroscopy.
