Abstract
Abstract A curable composition of a vinyl ether resin and at least one ferricenium salt of the formula: ##STR1## where R 1 , R 2 , R 3 and R 4 are the same or different H or alkyl groups or a linkage to a polymer backbone; M is a metal or metalloid; X is a halide; and n is an integer equal to 1 plus the valency of M.

Claim 3
Dependent Claim
23 words
A composition in claim 1 formed by addition of a trityl salt to a composition comprising a vinyl ether monomer and a ferrocene.
Claim 4
Dependent Claim
18 words
A composition as in claim 1 wherein M is selected from arsenic, antimony, phosphorus, boron, tin or bismuth.
Claim 5
Dependent Claim

Claim 9
Dependent Claim
115 words
A composition as in claim 1 wherein the vinyl ether is represented by one of the formulas: (CH.sub.2 ═CH--O--CH.sub.2).sub.n --G (CH.sub.2 ═CH--O--C.sub.6 H.sub.4).sub.n --G (CH.sub.2 ═CH--O--CR.sup.1 ═CR.sup.2).sub.n --G CH.sub.2 ═CH--O--C.tbd.C).sub.n --G or ketene acetals such as those of the formulas: ##STR5## where G is a mono or multivalent radical free of groups, such as amino, substituted amino or phenol, which interfere with cationic or free radical polymerization; n is an integer greater than or equal to 1; R 1 and R 2 are selected from H, alkyl, substituted alkyl, aryl, and substituted aryl; R 3 is selected from alkyl, substituted alkyl, aryl, and substituted aryl; and X is a hydrocarbonyl group of 1-5 carbon atoms.
