Abstract
Some new fluorosurfactants, containing poly (N-acylalkyleneimine) portion as a hydrophilic group, were prepared by polymerization of 2-alkyl-2-oxazoline and-2-oxazine initiated by p-toluene sulfonates having perfluoroalkyl group (A, B) (Scheme 1).
These polymers were found to have good reducing power of surface tension, e. g., γ=14.3dyn/cm for aqueous solution of MeOZO-A-5 and γ=18.4dyn/cm for ethylene glycol solution of EtOZO-A-7. The polymers showed a higher cloud point, especially MeOZO and MeOZI polymers remained clear at heating upto 100°. For fluorocarbon EF-L102 emulsion the polymers showed to have a higher stabilizing power than Pluronic F-68, but for xylene emulsion a lower one than F-68.
