Abstract

1,136,443. Anionic polymerization of lactams. INVENTA A.G. FUR FORSCHUNG PATENTVERWERTUNG. 31 Oct., 1966 [5 Nov., 1965], No. 48753/66. Heading C3R. Compounds where R 1 and R 2 are each alkyl and contain a total of 2 to 9 carbon atoms are used as promoters for the alkaline polymerization of lactams. Specified lactams contain 6 to 12 C atoms in the ring and optionally condensed cycloalkyl rings, e.g. 6,7-cyclopentano-#-enantholactam; they may be homo- or co-polymerized. In the example, capolactam is polymerized using N-butyl-N-chlorocarbonyl-N-(1- chloro-1-butenyl)-amine as promoter for sodium hydride catalyst.
