| abstract | A METHOD AND APPARATUS FOR CONTROLLING POLYAMIDE CONTINUOUS POLYMERIZATION TO OBTAIN SUBSTANTIALLY CONSTANT POLYMER PROPERTIES, PARTICULARLY AS MEASURED BY AMINE END GROUPS, CARBOXY END GROUPS AND RELATIVE VISCOSITY. SUBSTANTIALLY CONSTANT POLYMER PROPERTIES ARE OBTAINED EVEN WITH CHANGES IN THE RATE AT WHICH THE PRODUCED POLYMER IS REMOVED OR EXTRUDED FROM THE MELT COLLECTING ZONE. THE CONTROL IS ACHIEVED BY NUCLEAR RADIATION SENSING OF THE LIQUID LEVEL OF THE PRODUCED POLYMER IN THE POLYMER HOLDING RESERVOIR AND CONTROLLING THE INPUT OF FEED MATERIAL INTO THE REACTOR BASED ON SAID LEVEL SO AS TO ACHIEVE A SUBSTANTIALLY CONSTANT HOLDING PERIOD OF MOLTEN POLYMER PRIOR TO BEING EXTRUDED OR SPUN INTO FILAMENTS. |
