Abstract
Abstract Fluoroaliphaticsulfonyl substituted ethylenes, useful as catalysts in polymerization of monomers, e.g., epoxide, vinyl ether, and N-vinyl monomers, are prepared by condensation of precursor fluoroaliphaticsulfonyl methanes with aldehydes or N-formyl compounds.

Claim 1
Independent Claim
146 words
A fluoroaliphaticsulfonyl ethylene compound especially suited as a catalyst in epoxide, vinyl ether, and N-vinyl monomer polymerization and having the formula wherein R f is monovalent, saturated fluoroalkyl radical having from 1 to 18 carbon atoms; X is a monovalent, nonionic, electron withdrawing radical at least as electron withdrawing as a benzoyl radical selected from the group consisting of a cyano, phenylcarbonyl, alkylcarbonyl, perfluoroalkylcarbonyl of 2 to 18 carbon atoms, phenylsulfonyl, perfluoroalkylsulfonyl of 1-18 carbon atoms, nitro, fluorosulfonyl, or chlorosulfonyl group; R is hydrogen, an alkyl group, or a phenyl group; R' is the same as R with at least one being hydrogen; n is an integer from 0 to 7 depending on Z; n is 1 to 7 when Z is 2-furyl; n is zero when Z is a monovalent unsaturated, conjugated heterocyclic organic radical selected from the group consisting of furyl, thenyl and 1H-pyrrolyl.
