Photoinduced Depolymerization of Poly(olefin sulfone)s Possessing Photobase Generating Groups in the Side Chain

Abstract

A series of poly(olefin sulfone)s possessing photobase generating groups was synthesized, and photochemically induced depolymerization was investigated. The photobase generating groups used in this study produce primary or secondary amino groups by UV irradiation. The photochemically produced base extracts protons from the main chain of the poly(olefin sulfone) and induces a depolymerization reaction.
