| Abstract: | A photosensitive oligomer,cycloaliphatic epoxy polysiloxane,and a new kind of cationic photoinitiator,CpFe(η 6 tol)]BF 4,was synthesized.The influences of photoinitiators,ratio of oligomer to monomer,and promoters on the rate of photoinitiated cationic polymerization of cycloaliphatic epoxy polysiloxane systems were studied.It shows that the polysiloxane is a high photosensitive oligomer,with a 165 mL/cm 2 optimized photosensitivity when initiated by diaryliodonium salt SR 1012 with sensitizer 651. Moreover,the ability of dark cure of the polysiloxane when initiated by CpFe(η 6 tol)] BF 4was discussed. |
