Abstract

A chemiluminescent composition comprising an oxalate component comprising polystyrene or homopoly-.alpha.-methylstyrene containing an oxalate ester; an activator component comprising a solution of a peroxide compound and a catalyst in a first solvent; and a fluorescer contained in the oxalate component, activator component, or in both the oxalate component and the activator component. The first solvent is preferably a propylene glycol dialkyl ether. The chemiluminescent composition, when activated, permits light to be produced of controllable duration.

Dependent claims

A chemiluminescent composition comprising:

a) an oxalate component comprising a polymer containing an oxalate ester, said polymer being selected from the group consisting of homopolystyrene and homopoly-.alpha.-methylstyrene;
b) an activator component comprising a solution of a peroxide compound and a catalyst in a first solvent comprising a propylene glycol dialkyl ether containing one to three propylene moieties and each alkyl group is independently a straight-chain or branched-chain alkyl group containing up to 8 carbon atoms;
and
c) a fluorescer present in the oxalate component, activator component, or in both the oxalate component and the activator component.
