Abstract: The invention is directed to fluorinated alkylamido sulfonic acids and salts of the formula ##STR1## where R.sub.f is straigt or branched chain perfluoroalkyl of 1 to 18 carbon atoms or perfluoroalkyl substituted by perfluoroalkoxy of 2 to 6 carbon atoms, R.sub.1 is hydrogen or lower alkyl and each of R.sub.2, R.sub.4 and R.sub.5 is individually hydrogen or a hydrocarbon radical, and R.sub.6 is alkylene, alkylenethioalkylene, alkyleneoxyalkylene or alkyleneiminoalkylene with a secondary or tertiary nitrogen atom. R.sub.3 is hydrogen, alkyl, aryl or pyridyl, M is hydrogen, a monovalent alkali metal, an alkaline earth metal, an organic base or ammonium, and n is an integer corresponding to the valency of M. Said compounds are prepared by a base catalyzed addition reaction of the thiol, R.sub.f -R.sub.6 SH, to an alkyenylamido sulfonic acid salt. The compounds are useful as surfactants and as levelling agents in floor polish formulations.

Abstract: The invention is directed to alkylthio alkylamido sulfonic acids and salts of the formula ##STR1## R.sub.6 is unsubstituted or substituted alkyl, cycloalkyl or phenyl, alkylthio, tert-alkylamine, furfuryl or a group derived from a polyfunctional mercaptan, R.sub.1 is hydrogen or lower alkyl and each of R.sub.2, R.sub.4 and R.sub.5 is individually hydrogen or a hydrocarbon radical. R.sub.3 is hydrogen, alkyl, aryl or pyridyl, M is hydrogen, a monovalent alkali metal, an alkaline earth metal, an organic base or ammonium, and n is an integer corresponding to the valency of M. Said compounds are prepared by a base catalyzed addition reaction of a reactive mercaptan to an alkylenylamidoalkane sulfonic acid salt. The compounds are useful as surfactants.

Abstract: Vinyl ester homopolymers and copolymers containing hindered phenolic groups are novel materials which are useful as antioxidants. These polymers protect against oxidative and thermal degradation or deterioration of organic materials in general and more particularly synthetic polymers such as polyolefins. The vinyl ester polymers are obtained by subjecting to polymerizing conditions (a) a vinyl ester monomer containing a hindered phenolic group, either alone or with another comonomer and (b) a free radical initiator.
