Abstract
A flame-retardant composition is described comprising a mixture of a water dispersible organic polymer; and a water dispersible derivative of an unsaturated dicarboxylic acid or anhydride thereof. The water dispersible derivative typically has a solubility in a 0.1 N aqueous solution of NaOH at 25° C. of at least 25 g/liter. Also described is a flame-retardant composition comprising the mixture described dispersed in an aqueous carrier and method of making a flame-retardant composition.
