Disclosed is a method for forming a polyacetal in which free hydroxyl groups or other functional groups that are not stable under conventional polyacetal formation conditions are present in the side chain. A method for forming a polyacetal from a bis (aryl) acetal having the following structure by a coupling reaction in which a carbon-carbon bond is formed in the presence of a catalyst and a base. Wherein Y is a leaving group selected from chloro, bromo, iodo, mesylate, tosylate, triflate, or a boron-containing functional group, Ar is an aryl group, and at least one of the aryl groups is a hydroxyl group , Substituted with at least one functional group selected from the group consisting of acetals, ketals, esters and lactones) [Selection figure] None |
