Photopolymerizable compositions that include alicyclic/aromatic dioxiranes and novel dioxiranyl tetraoxaspiro [5.5] undecanes

摘要

A visible light cationically photopolymerizable composition is provided. This composition includes an expanding monomer and a dioxirane. More specifically, the expanding monomer used in this composition is one or more dioxiranyl tetraoxaspiro[5.5]undecanes. The composition of the present invention may be used as a matrix resin for dental restorative materials. Another embodiment of the present invention is various novel dioxiranyl tetraoxaspiro[5.5]undecanes.
