ABSTRACT:
Iodonation of novolak resin or polyphenylene ether followed by the metatheses of the resulting iodonated product with a polyhalometal or metalloid salt can provide a photoactive cure catalyst or thermally active cure catalyst for cationically polymerizable organic materials. A copper cocatalyst has been found useful in thermal curing.
