Abstract: PROCESS AND APPARTUS FOR PREPARING A CATALYST FOR THE ANIONIC POLYMERIZATION OF LACTAMS, IN WHICH A LACTAM AND A ALKALI METAL HYDROXIDE ARE CONTINOUSLY FED INTO A FIRST REACTION VESSEL THE LIQUID LEVEL IN SAID VESSEL BEING KEPT CONSTANT BY FEEDING A PORTION OF THE REACTION MIXTURE INTO A SECOND VESSEL AND THE LIQUID LEVEL IN SAID SECOND VESSEL BEING KEPT CONSTANT BY DISCHARGINGG A CONTINUOUS STREAM OF THE REACTION MIXTURE FROM SAID VESSEL. THE WATER FORMED IN THE REACTION VESSELS IS EVAPORATED BY HEATING IN VACUO AND THE VAPOUR THUS FORMED IS PASSED THROUGH A CONDENSER IN WHICH THE LACTAM IS CONDENSED AND RETURNED TO THE REACTION VESSELS.

Abstract: THE USE OF CARBOXYLIC ESTERS OF KETOXIMES, IN WHICH AN ACYL RADICAL HAS BEEN SUBSTITUTED IN THE MOLECULE FOR ONE OF THE HYDROCARBON RADICALS OF THE KETOXIME, AS PROMOTERS, USED IN CONJUNCTION WITH CATALYSTS, IN THE IONIC POLYMERIZATION OF LACTAME, IS DISCLOSED. THE USE OF SUCH PROMOTERS PERMITS RAPID POLYMERIZATION WITH HIGH YIELDS OF AMIDE POLYMERS, WHICH ARE USEFUL IN THE PRODUCTION OF MOLDED PRODUCTS.
