ABSTRACT:
Photosensitive iodonium polymers are provided useful as positive photoresists. The iodonium polymers can be converted to polymeric diaryl iodonium polyfluorometal and metalloid salts by a metathesis reaction. These polymeric iodonium polyfluorometal and metalloid salts can be used as a catalyst in combination with a copper compound cocatalyst to make heat curable compositions with cationically polymerizable materials such as an epoxy resin.
