Polymeric Imaging Material Based on an Acid-Catalyzed Main-Chain Cleavage Reaction

A novel polymeric imaging material containing polyacetal and photoacid generator has been designed. The polyacetal having acetals in its main chain was prepared by condensation of a monomer containing both a carbonyl and a diol group and also it was reverted to the monomer through an main chain cleavege reaction catalyzed with photogenerated acid.
