摘要：
Zinc-based metal complexes (ZnC) are proposed as original photoinitiators in multi-component systems for the formation of free radicals under visible light irradiation. The ZnC/iodonium salt/additive three-component systems (where the additive can be a silane or a divinyl ether) present an excellent ability to promote either the free radical polymerization of an acrylate, the cationic polymerization of a divinyl ether and the polymerization of acrylate/vinyl ether blends under very soft irradiations (e.g. halogen lamp irradiation) or laser diodes (457 or 532 nm) exposure. The mechanisms are investigated by photolysis, luminescence and ESR experiments. (C) 2013 Elsevier Ltd. All rights reserved.
