Abstract:
1. A flame retardant comprising an ion complex formed from compounds including at least one first compound each selected from sulfuric acid or an organic compound having a sulfonic acid group and a second organic compound each having a cationic moiety, the ionic complex including ionic bonding of sulfuric acid or a sulfonic acid group in the at least one first compound and at least one cationic moiety in the at least one second organic compound, and at least one of the at least one first compound or the at least one second organic compound being a polymer, wherein the at least one first compound further includes a compound that has a cationic moiety ionically binding to sulfuric acid or a sulfonic acid group in another molecule of the at least one first compound, wherein the other molecule of the at least one first compound may be the same as or different from the compound of the first compound having the cationic moiety, in a case in which the at least one first compound is a polymer, the at least one first compound is selected from a polymer or copolymer of acrylamidemethylpropanesulfonic acid, or a polymer or copolymer of styrenesulfonic acid; and in a case in which the at least one second organic compound is a polymer, the at least one second organic compound is selected from polyethyleneimine, polypropyleneimine, polyallylamine, or a copolymer thereof.
