ABSTRACT:
An aqueous, resinous solution of a curable, polymeric reaction product, the cured polymeric flame resistant coating and methods for producing them are provided. The solution is formed by direct reaction or prepolymer reaction and chain extension reaction of a methylol and/or hydroxyl-containing quaternary phosphonium compound, divalent nitrogen-containing compound and a heteroatom-containing compound. A nitrogen-containing compound has at least 2 active hydrogen and/or methylol radicals. The direct or prepolymer reaction has present a tertiary amine.
