摘要：

Bis(4-methoxybenzoyl) diethylgermane (BMDG) is used for the photopolymerization of six 1,1-disubstituted 2-vinylcyclopropanes (VCPs). A significantly higher photo-polymerization reactivity compared to the conventional camphorquinone (CQ)/amine or CQ/amine/iodonium salt photoinitiator systems is observed. Furthermore, the influence of the electron-withdrawing substituents on the monomer reactivity is investigated. 1-Ethoxycarbonyl-1-ethylcarbamoyl2-vinylcyclopropane 5 and 1-ethoxycarbonyl-2-vinylcyclopropanecarboxylic acid 2 are found to be the most reactive monomers. 1,1-Disubstituted VCP-based dental composites containing BMDG are formulated. Those materials exhibit good mechanical properties as well as a low polymerization shrinkage.
