Use of sulfonic acid salts in cationic polymerization

Abstract

Abstract 1. THE PROCESS COMPRISING THE STEPS OF MIXING CATIONIC SENSITIVE MONOMER WITH A CATALYST CONSISTING OF SULFONIC ACID SALT AND HEATING THE RESULTING MIXTURE AT 120 TO 425* F. TO EFFECT CURE THEREOF IN THE ANSENCE OF HALIDE PROMOTER, PHOTOREDUCIBLE KETONE, OR WITHOUT REQUIRING ACTINIC LIGHT, WHEREIN SAID MONOMER IS AN ETHYLENICALLY UNSATURATED HYDROCARBON, AN ETHYLENICALLY UNSATURATED COMPOUND HAVING AN OXYGEN OR NITROGEN ATOM ATTACHED TO ONE OF THE CARBON ATOMS OF A CARBON-TO-CARBON DOUBLE BOND OR IS POLYMERIZABLE BY RING OPENING OF CYCLIC GROUPS CONTAINING A HETERO OXYGEN OR NITROGEN RING ATOM, AND IS SELECTED FROM THE GROUP CONSISTING OF VICINAL EXPOXIDES, VINYL ETHERS, N-VINYL COMPOUNDS, AZIRIDINES, ETHYLENICALLY UNSATURATED HYDROCARBONS AND ACETALS AND SAID SULFONIC ACID SALT HAS THE FORMULA (RFSO3)NM, WHERE RF IS FLUOROALKYL HAVING 1 TO 18 CARBON ATOMS, M IS AMMONIUM CATION, QUATERNARY AMMONIUM CATION, CATION OF AMINE, OR COTION OF METAL SELECTED FROM GROUPS I TO V AND VIII, SUBGROUPS VI-B AND VII-B, AND LANTHANIDE AND ACTINIDE SERIES OF METALS OF THE PERIODIC TABLE, AND N IS AN INTEGER EQUAL TO THE VALENCE OF M.
