Abstract
Polyacetals and polyketals are prepared by reacting emulsified carbonyl compounds with emulsified polyfunctional alcohols in aqueous media and in the presence of specified polycondensation catalysts. Coherent films of the resultant polymers can be applied to substrates from aqueous or non-aqueous media.
