Abstract
This invention relates to water soluble fluorochemical foam stabilizers and film formers derived from polyamines, perfluoroalkyl group containing esters or acid halides and hydrophilic and hydrophobic group containing compounds which react with primary, secondary and tertiary amino groups. The novel foam stabilizers and film formers are useful as additives for aqueous film forming foam fire fighting agents improving the foam stability against polar solvents and enhancing the fire fighting performance.
