CONCLUSIONS
EB Technology; C. Cordon, C. Miller, Eds.; RadTech Interna-
In this paper, two D-p-A structured trifluoroacetophenone-
based photoinitiators with phenyl and fluorenyl linking groups
are prepared, and both possess excellent light absorption
capacity. The UV-Vis spectra, fluorescence, electrochemistry, and
ESR-ST experiments demonstrate that the two acetophenone-
based photoinitiators combined with various additives (i.e.,
amine [MDEA], Iod, and N-vinylcarbazole [NVK]) are able to effi-
ciently produce reactive radicals and cations and then induce
FRP of acrylates in laminate and the cationic polymerizations of
epoxides and vinyl ether under air upon exposure to 365–
