  • Composition for producing chemiluminescent light of controllable duration
    Patent number: 5705103
    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.
