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.
