Synthesis of Poly(olefin sulfone)s That Release Low-Molecular-Weight Bases by Light Absorption and Investigation of Their Photoinduced Depolymerization.

ABSTRACT: Poly-(olefin sulfone)-s react with bases, leading to a depolymerization reaction, and convert themselves into monomers. A poly-(olefin sulfone) with an incorporated photobase generator undergoes depolymerization when exposed to light and subsequently heated. In previous studies, low-molecular-weight photobase generators have been mixed with poly-(olefin sulfone)-s or have been introduced onto their side chains. A photobase generator in a side chain decomposes when it is exposed to light, and a base attached to the main chain is generated. In the present study, we synthesized novel poly-(olefin sulfone)-s in which a photobase-generating moiety that releases a low-molecular-weight base is introduced into the side chains. In the polymers synthesized in this study, the photobase generator is u
