Abstract
Process for obtaining polymerization products by polymerization of cyclic acetals, optionally together with other cationically polymerizable compounds in the presence of catalysts and, if necessary, indifferent solvents at temperatures between -70º C and +150º C, characterized in that as catalysts, fully esterified polyphosphoric acids are used.
