Abstract: The invention relates to a method for the continuous production of copolyamides which are based on a lactame (I), a diamine (II) and a dicarboxylic acid (III). The inventive method is characterised in that a mixture (IV) containing a diamine (II), a dicarboxylic acid (III) and water is converted to a polymer in a first reaction area at a pressure of 1,3*10 5 to 2,5*10 5 Pa in the entry part of the reaction area, at a temperature above the melting point of the polymer (V) and with a degree of conversion of at least 80 %  in relation to the molar quantities of diamine (II) and dicarboxylic acid (III), in that a mixture (VI) containing lactame (I) and water is converted to a polymer (VII) in a second reaction area at a pressure of 5*10 5 to 40*10 5 Pa, at a temperature above the melting point of the polymer (VII) and with a degree of conversion of at least 80 % in relation to the molar quantity of lactame (I), in that polymer (V) and polymer (VII) are then reacted with each other in a third reaction area at a pressure of 1*10 5 to 1,5*10 5 Pa in the entry part of the reaction area, at temperatures above the melting temperature of the polymer (VIII), to produce the polymer (VIII). Polymer (VIII) contains a maximum of 10 wt. % constituents that are extractable with water at a temperature of 95 °C, in relation to lactame (I), diamine (II) and dicarboxylic acid (III). The polymer (VIII) is then extracted with water so as to obtain the copolyamide. The invention also relates to copolyamides obtained using this method and to their use in the production of fibres, sheet structures and moulded bodies which are based on these copolyamides.

Abstract: La présente invention concerne un procédé qui permet d'examiner la paroi (2) d'un trou de forage présent dans une formation géologique au moyen de deux injecteurs (4, 5) de courant I. Dans le procédé, on applique un potentiel V entre les deux injecteurs puis on mesure la différence de potentiel .delta.V entre deux électrodes (6) de mesure isolées du point de vue électrique situées entre les deux injecteurs (4, 5) et espacées de la formation par une couche isolante (1) ; la résistivité de la formation découlant des valeurs mesurées de .delta., de V, et de I, auxquelles on applique des corrections pour les effets induits par la nature et l'épaisseur de la couche isolante (1). Dans une première forme de réalisation, ces corrections sont fondées sur un facteur de correction provenant des courbes de k = Rt.I/.delta.V en fonction de l'impédance V/I de l'injecteur. Dans une deuxième forme de réalisation, ces corrections proviennent de l'estimation du courant I¿F? effectivement injecté dans la formation dans laquelle on prend en compte le courant de fuite L¿L?, et du calcul de la résistivité de la formation issue de l'équation (I). Cette invention concerne également un dispositif d'investigation qui permet d'estimer les valeurs de I¿F? et/ou de I¿L?. Equation (1)
