Photopolymerization of OCDMA Dimetacrylate Initiated by 3,5-Di-tert-Butyl-o- Quinone and its Bis-O-Benzoquinone

Abstract

The reactivity of 3,5-di-tert-butyl-o-benzoquinone and its bis-o-benzoquinone derivative in photoreduction reaction and polymerization of dimethacrylate (OCDMA) (in bulk and in the presence of 1-butanol) with using of them as photoinitiators under visible light irradiation under argon atmosphere or air were investigated. It was found that the kinetic parameters of the bis-o-quinone photoreactions have low sensitive to the presence of molecular oxygen. The high stability of the spectral characteristics of resulting polymers based on bis-o-quinones compositions for the long time was established.
