Acidolysis of Poly(4-Methyl-1,3-Dioxolane).
Abstract
The onset of decomposition of poly(4-methyl-1,3-dioxolane) was lowered from 70 degs. by 0.1 weight % p-toluene sulfuric acid to 170 degs. producing more than 81% yield of monomer. Protonation forms cyclic oxonium ion followed by depolymerization. Minor products are isomers of hydroxymethyl-2-hydroxyl-2-methyl ethyl ether and bis(2-hydroxyl-2-methyl ethoxyl)methane rearrangements of the oxonium ions. The first order rate constant of acidolysis of poly(4-methyl-1,3-dioxolane) is ca. 8.5 kcal/mole which is much smaller than about 17 kcal/mole for the acidolysis of poly(1,3-dioxolane).
