Abstract: Anionic polymerization of lactams is carried out in an extruder into which at least one lactam, at least one catalyst and at least one activating agent are introduced and wherein the mixture of said substances is polymerized prior to being extruded through an extrusion die. The output rate of the polymerized substance is controlled by transfer means, such as a metering pump, arranged between the outlet of the body of the extruder and the extrusion die.

Abstract: The invention relates to a process for the preparation of lactames according to the so-called "Beckmann rearrangement" which consists in isomerizing oximes in a sulfuric solution, the weight ratio percentage of sulfuric acid to the combined amount of sulfuric acid and water being raised to a value above that of the sulfuric solution feed.

Abstract: 1345666 Polylactam treatment SOC AQUITAINE-TOTAL ORGANICO OF TOUR AQUITAINE 24 Aug 1972 [25 Aug 1971] 39433/72 Heading C3R Polyamides prepared by anionic polymerization of a lactam in anhydrous medium with an alkaline catalyst, are treated by addition of a tertiary alcohol R 1 R 2 R 3 COH, where R 1 , R 2 , and R 3 are hydrocarbyl. The alcohol may be tertbutyl alcohol. The lactam may be capro-, dodeca-, or capryl-lactam. There maybe 0À05-2 moles alcohol per mole lactam. The alcohol may be added after polymerization, e.g. by mixing with the polyamide in molten or paste form. Use.-Fibres, films, sheets, moulded articles.
