Polyacetals, owing to the acid sensitivity of the acetal linkage, are attractive candidates for end uses in which acid sensitivity is a desirable property, e.g. photo- or electron-resists. Many polysaccharides belong to this general class and owe many of their special properties to the acetal linkage. We report here a study of acid-catalyzed decomposition of poly2-butyl-1,36-trioxocane under two sets of conditions mild leading to depolymerization, and drastic leading to more profound degradation. A mechanism for depolymerization involving open chain oxy-carbocation intermediates operates.
