In a method of forming a polyacetal or polyketal, a specific acetal- or ketal-containing bis(aryl)acetal is coupled with itself or a comonomer in the presence of a catalyst and a base. The polymerization reaction tolerates hydroxyl and other functional groups on the bis(aryl)acetal. Among other applications, the polyacetals and polyketals are useful components of photoresist compositions. |
