Abstract
Ferricenium salts of the formula: ##STR1## where R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are the same or different H or alkyl groups or a linkage to a polymeric backbone: M is a metal or metalloid; X is a halide and n is an integer, induce polymerization of acrylic monomer/peroxy initiator systems. Above a certain minimum concentration, however, gel time of the composition increases with additional ferricenium salt. This property is especially useful for controlling pot life of an activated acrylic composition.
