Abstract
Abstract Novel, high light capacity chemiluminescent systems are disclosed. The high capacity is produced by adding a small amount of a polymer selected from the class consisting of: (1) homopolymers and copolymers of poly(alkylene oxides); (2) homopolymers and copolymers of poly(vinyl alkyl esters) and poly(vinyl alkyl ethers) with the optional inclusion of minor amounts of alkylenes and styrenes in said copolymers; (3) 1:1 alternating copolymers of maleic anhydride with alkylenes and styrenes; (4) cellulose esters and mixed cellulose esters of 2-, 3- and 4-carbon acids and mixtures of said esters with the poly(alkylene oxides), to a chemiluminescent system containing a bisaryloxylate, an organic fluorescer a peroxide, and an organic solvent.
