**9. Conclusions**

Photoinduced depolymerization of poly(olefin sulfone)s containing photobase generators was summarized. Since poly(olefin sulfone)s are copolymers of olefins and sulfur dioxide, the sulfur dioxide produced through the depolymerization evaporates from the system. Thus, the depolymerization reaction proceeds only in one direction, and the polymer is converted into consistent olefins. The photoinduced depolymerization of poly(olefin sulfone)s has been investigated for a wide variety of applications, including stereolithography, printable microcircuit fabrication, and detachable adhesives.
