CATALYST SOLUTION FOR THE ANIONIC POLYMERIZATION OF LACTAMS AND THEIR USE FOR THE ANIONIC POLYMERIZATION OF CAPROLACTAM.

摘要

CATALYST SOLUTION FOR THE ANIONIC POLYMERIZATION OF LACTAMS, CONTAINING 30 TO 45% BY WEIGHT OF A LACTAM WITH AT LEAST 7 ANNULAR MEMBERS WITH A CONTENT OF ALKALINE METAL OF 3 TO 5% BY WEIGHT IN THE FORM OF AN ALKALINE LACTAM, 3 TO 8% IN WEIGHT OF 2-PIRROLIDONE, 15 TO 20% IN WEIGHT OF POLY-C SUB 1-C SUB 4-ALKYLENE GLYCOL WITH A MOLECULAR WEIGHT OF 250 TO 350, UP TO 5% IN WEIGHT OF A MONKEY AND / OR PRIMARY POLYAMINE AND / OR SECONDARY SCHOOL WITH A BOILING POINT UNDER NORMAL PRESSURE ABOVE 250 C AND UP TO 40% BY WEIGHT OF AN AROMATIC HYDROCARBON WITH A BOILING POINT OF 80 TO 145 C, COMPLETING THE SUM OF THE PERCENTAGES OF WEIGHT TO 100, RESPECTIVELY.
