Abstract

Abstract : Bulk photo-CuAAC networks are rapidly polymerized under blue light using novel photoinitiator system avoiding azide decomposition, yielding glassy, transparent films with narrow glass transition region. Abstract : A visible-light (470 nm wavelength) sensitive Type II photoinitiator system is developed for bulk Cu(i )-catalyzed azide–alkyne cycloaddition (CuAAC) reactions in crosslinked networks. The accelerated photopolymerization eliminates UV-mediated azide decomposition allowing for the formation of defect-free glassy networks which exhibit a narrow glass transition temperature.
