POLY-PERFLUOROALKYL SUBSTITUTED POLYAMINES AS GREASE PROOFING AGENTS FOR PAPER AND FOAM STABILIZERS IN AQUEOUS FIRE-FIGHTING FOAMS

摘要

Perfluoroalkyl-allyloxy- and perfluoroalkyl-iodopropyloxy-substituted polyaminoacids or poly- R F-fluoroallyl-substituted polyaminoacids which contain, in random distribution, q units of A-1, r units of A-2, s units of A-3 and t units of A-4 in which A-1 and A-2 are perfluoroalkyl-substituted amino groups of the formulae (see formula A-1) and (see formula A-2) A-3 is a hydrophilically substituted amino or amido group of the formula (see formula I) (see formula II) or (see formula III), and A-4 is a substituted amino or amido group of the formula (see formula IV) (see formula V) or (see formula VI), where the variables are as defined herein, are useful to provide oil repellency to paper and as foam stabilizers in alcohol resistant - aqueous fire-fighting foam fire- fighting foam compositions.
