ABSTRACT:
Disclosed are siloxanyl-substituted diaromatic iodonium salts such as 4-[3-1,1,3,3,5,5,5-heptamethyl siloxanyl propoxy]phenyl-phenyliodonium hexafluoroantimonate. These diaryl iodonium salts are useful as photoinitiators for epoxy containing compounds, especially epoxypolysiloxanes. Also disclosed is a process for the preparation of a siloxanyl-substituted diaromatic iodonium salt.
