Continuous polymerization of acrylonitrile and mono-ethylenically unsaturated quaternary ammonium salts
Abstract
Abstract IN THE PROCESS OF CONTINUOUSLY POLYMERIZING ACRYLONITRILE WITH A MONOETHYLENICALLY UNSATURATED QUATERNARY AMMONIUM SALT IN AN EQUEOUS ACIDIC REACTION MASS CONTAINING A WATER-SOLUBLE INORGANIC FREE RADICAL GENERATING POLYMERIZATION CATALYST TO PRODUCE POLYMERS CONTAINING 50 TO 70 PERCENT ACRYLONITRILE AND 30 TO 50 PERCENT MONOETHYLENICALLY UNSATURATED QUATERNARY AMMONIUM SALT, THE IMPROVEMENT COMPRISING PERFORMING SAID POLYMERIZATION IN THE PRESENCE OF A CONCENTRATION OF NITRATE IONS IN SAID REACTION MASS EQUAL TO AT LEAST 80 PERCENT OF THAT STOICHIOMETRICALLY EQUAL TO THE CONCENTRATION OF MONOETHYLENICALLY UNSATURATED QUATERNARY AMMONIUM SALT IN SOLUTION THEREIN AND SUFFICENT TO KEEP SAID REACTION MASS FLUID.
