Abstract: 2-(2-Hydroxy-3-perfluoroalkylthiomethyl-5-alkylphenyl)-2H-benzotriazoles are prepared by reacting the Mannich base hydrohalide or quaternary salt of a 2-(2-hydroxy-5-alkylphenyl)-2H-benzotriazole with a perfluoroalkyl mercaptan. The products exhibit outstanding efficacy in protecting organic substrates from light induced deterioration as well as good resistance to loss by volatilization or exudation during the processing of stabilized compositions at elevated temperatures.

Abstract: The instant invention relates to water-soluble anionic polysaccharides bound to perfluoroalkyl cationic surfactants. Polymer complexes are formed which are especially useful for fighting fires of hydrophilic or polar liquids. They have the unique property of forming an impervious gel when foamed with suitable surfactants and projected onto burning liquids. The gelatinous blanket is resistant to the fuel and protects the foam blanket from destruction. Consequently, superior fire-fighting agents can be prepared for fires which are otherwise very difficult to extinguish.
