T. Marino et al., POSTCURE EFFECTS ON PHOTOPOLYMERIZATION USING VISIBLE-LIGHT INITIATORS, Industrial & engineering chemistry research, 34(12), 1995, pp. 4549-4552
In a continuing study of the visible light initiator 2,4-diiodo-6-buto
xy-3-fluorone (DIBF), significant postcure was observed in the polymer
initially formed from unsaturated polyester resins under both aerobic
and anaerobic conditions either in the presence of or without ambient
light. The extent of postcure varies with the test conditions. A tent
ative explanation is proposed.
