Abstract: Procedimientos para la obtencion de caprolactama, así como procedimientos para la obtencion de polímeros usando caprolactama son generalmente conocidos. Los procedimientos de purificacion del producto citado obtenido tienen la desventaja, que son técnicamente complicados y requieren mucha energía, especialmente, por las numerosas etapas de separacion. Se provee un procedimiento que permite obtener polímeros a base de caprolactama de manera técnicamente sencilla y con ahorro de energía, obteniéndose polímeros con índices característicos de producto comparables con polímeros a base de caprolactama purificados mediante procedimientos técnicamente más complicados y con mayor consumo de energía. Procedimiento para la obtencion de un polímero usando caprolactama en donde: a) se hace reaccionar una mezcla (I) que contiene 6-aminocapronitrilo y agua, dando una mezcla (II) que contiene caprolactama, amoníaco, agua componentes de alto punto de ebullicion y componentes de bajo punto de ebullicion, en presencia de un solido que fomenta catalíticamente la reaccion, luego b) se elimina el amoníaco de la mezcla (II), obteniéndose una mezcla (III) que contienen caprolactama, agua, componentes de alto punto de ebullicion y componentes de bajo punto de ebullicion, luego c) se elimina el agua parcial o completamente de la mezcla (III), obteniéndose una mezcla (IV) que contienen caprolactama, componentes de alto punto de ebullicion y componentes de bajo punto de ebullicion, y luego d) se polimeriza la mezcla (IV), así como un polímero obtenido segun este procedimiento, a su uso para la fabricacion de fibras, materiales de estructura plana y cuerpos moldeados, así como a fibras, materiales de estructura plana y cuerpos moldeados obtenidos usando tal polímero.

Abstract: The invention relates to a method for producing a polymer. Said method is characterized as follows: a) a mixture (I) containing 6-aminocapronitrile an d water is converted into a mixture (II) containing caprolactam, ammonia, wate r, high boilers and low boilers in the presence of a catalyst; then b) the ammonia is removed from mixture (II) to obtain a mixture (III) containing caprolactam, water, high boilers and low boilers; subsequently c) the water is completely or partially eliminated from mixture (III) to obtain a mixture (I V) containing caprolactam, high boilers and low boilers; and finally d) mixture (IV) is subjected to a polymerization reaction. The invention also relates t o a polymer obtained according to said method, to its use in the production of fibres, flat material and moulded bodies that are obtained using a polymer o f this type.

Abstract: Polyamides, oligomers thereof or mixtures thereof, if required with further reaction products, are prepared by reacting aminonitriles or dinitriles and diamines or a mixture containing aminonitrile, dinitrile and diamine, and, if required, further polyamide-forming monomers and/oligomers with water in a reactor ( 1 ) having a vertically oriented longitudinal axis, by a process in which, in the reactor ( 1 ), the reaction product is removed from the bottom and ammonia formed and any further low molecular weight compounds formed and water are taken off via the top ( 2 ), wherein the reactor ( 1 ) has at least two chambers ( 4 ) arranged one on top of the other in the longitudinal direction, the chambers ( 4 ) being separated from one another by liquid-tight trays ( 5 ), each chamber ( 4 ) being connected by a liquid overflow ( 6 ) to the chamber ( 4 ) directly underneath and a liquid product stream being taken off by the liquid overflow ( 6 ) of the lowermost chamber ( 4 ), the gas space ( 7 ) above the liquid level in each chamber ( 4 ) being connected to the chamber ( 4 ) arranged directly above in each case by one or more conduit pipes ( 8 ) which in each case opens or open into a gas distributor ( 9 ) having orifices ( 11 ) for gas exit below the liquid level, and comprising in each case at least one baffle plate ( 12 ) which is arranged vertically around each gas distributor ( 9 ) and whose upper end terminates below the liquid level and whose lower end terminates above the liquid-tight tray ( 5 ) of the chamber ( 4 ) and which separates each chamber ( 4 ) into one or more gassed ( 13 ) and into one or more ungassed ( 14 ) spaces.
