Description
Polyvinyl alcohols were acetalized with aldehyde sulfonic acids such as β-butyraldehyde sulfonic acid, o-benzaldehyde sulfonic acid and 2, 4-benzaldehyde disulfonic acid in solution. The maximum conversions of the reactions were generally much lower than the calculated value from Flory's theory, and dependent on the steric configurations of polymer and the compositions of the reaction mixtures. Steric hindrance and/or electrostatical effects by acetals introduced into the polymer chains seem to be the reasons for these results. Statistical calculations were given for the maximum conversions.
