摘要：

Two kinds of cyclophosphazenes, bearing UV-reactive acrylic groups (HACP) and non-reactive ethyl groups (HECP), respectively, were synthesized, and characterized by FTIR, H-1-, and C-13-NMR. These compounds were used as flame retardants to blend with commercial UV-curable epoxy acrylate EB600. The thermal behavior and degradation mechanism were monitored by TGA, in-situ FTIR and apparent activation energy calculation. The UV cured blends showed better thermal stability at elevated temperature with higher char yields compared with pure EB600 sample. The flame retardancy of the blends was examined by LOI measurements. and has shown that the blends with HACP or HACP powder have higher LOI than that with HECP. (C) 2004 Elsevier Ltd.
