Much of authors' recent work with imaging system which incorporate chemical amplification has involved the design of polymers which can undergo multiple main-chain cleavages as the result of a phototriggered process. They prepared dozens of new polycarbonates, polyethers and polyesters which are all susceptible to acid-catalyzed thermolytic cleavage. With all of these systems, imaging is accomplished through irradiation of a film of the polymer containing a small amount of a photoactive compound which can generate acid upon irradiation. The thermolysis of esters and carbonates is a well-known reaction which is particularly effective with tertiary alcohol derivatives. The authors extended it a variety of allylic and benzylic substrates for which a clean reaction requiring relatively low temperatures was predicted. In contrast, the clean thermolysis of appropriately chosen ethers into alkene and alcohol components was little known until this work.
