Abstract: A process for the continuous preparation of polycaprolactam, which comprises polymerizing epsilon -caprolactam in a vertical tubular reactor through which the epsilon -caprolactam flows downward, wherein the epsilon -caprolactam is partially polymerized, at a nylon-forming temperature, in a mechanically mixed zone, the reaction mixture is circulated through a heat exchange zone in the lower part of the mechanically mixed reaction zone, and is polymerized further, in additional heat exchange zones, until the desired degree of polymerization is reached, and poly- epsilon -caprolactam is then discharged as a melt, and an apparatus for carrying out the process.

Abstract: Nylons are prepared by a continuous process in which, in a precondensation zone, an aqueous solution of a salt of a dicarboxylic acid of 6 to 18 carbon atoms and a diamine of 6 to 18 carbon atoms is heated to 250 DEG -300 DEG C. under superatmospheric pressure, with simultaneous vaporization of water and formation of a prepolymer, the prepolymer and the vapor are separated, and the former is fed into a polycondensation zone and condensed under superatmospheric pressure of from 1 to 10 bar and at from 250 DEG to 300 DEG C., wherein the aqueous salt solution is condensed under superatomspheric pressure of from 1 to 10 bar in the first third of the tubular precondensation zone provided with baffles, until the degree of conversion is not less than 93%, and the prepolymer and the vapor phase are brought into intimate contact with one another in the remaining two thirds of the precondensation zone.

Abstract: Prodn. of polyamides (I) comprises polymerisation or polycondensation of monomers in presence of triacetone- diamine cpd(s) of formula (II), where R is H, 1-20C hydrocarbyl, pref. 1-18C alkyl, or benzyl. Also claimed are (i) inherently light-stabilised polyamides (I) with amine residues derived by removing H from the NH2 gp. of (II) chemically bonded to the polymer chain; (ii) a process for the prodn. of polycaprolactam-based filaments from (I), by high-speed spinning with take-off speeds of at least 4000 m/min.; (iii) filaments obtd. by this process; and (iv) fibres and textile sheets produced from the filaments.

Abstract: A process for the manufacture of a highly concentrated aqueous solution of a salt of a dicarboxylic acid and a diamine, as well as of a nylon precondensate, by reacting an alkanedicarboxylic acid of 6 to 12 carbon atoms and a diamine of the formula NH2RNH2, where R is alkylene of 6 to 12 carbon atoms or is An aqueous solution, of lower concentration, of a salt of a dicarboxylic acid and a diamine, containing an appropriate dissolved excess of the particular dicarboxylic acid, is reacted with the particular diamine in the molten state, in an equivalent amount to the dissolved dicarboxylic acid, the reaction being carried out under superatmospheric pressure and the final reaction temperature being kept at from 140 DEG to 210 DEG C. The solution obtained is used for the manufacture of a nylon.

Abstract: The prodn. of polyamides (I) comprises polymerisation or polycondensation of the corresp. monomers in the presence of triacetone-diamine cpd(s). of formula (II). R = H or 1-20C hydrocarbyl, pref. 1-18C alkyl or benzyl. Also claimed are polyamides with inherent thermal stability, contg. a -NH-linked residue derived from (II) in the polymer chain. Also claimed is a process for the prodn. of filaments based on polycaprolactam modified with (II) as above, by melt spinning with take-off speeds of at least 4000 m/min.

Abstract: Filaments with a relative viscosity RV of 2.0 to 3.0 (measured at a concentration of 1 g of fibres per 100 ml in a 96 wt % sulphuric acid) based on polycaprolactam, obtainable by: (a) extruding a melt consisting essentially of caprolactam through a spinning nozzle to form caprolactam filaments; (b) cooling the filaments thus produced and (c) drawing the cooled filaments off at a rate of at least [3600 + 1250.(3.0 - RV)] m/min, the polycaprolactam used being produced in the presence of at least one bicarboxylic acid from the group: C4-C10-alkane bicarboxylic acids, C5-C8-cycloalkane bicarboxylic acids, benzole and naphthaline bicarboxylic acids which may have up to two sulphonic acid groups and whose carboxylic acid groups are not adjacent, N-C1-C6-alkyl-N,N-di(C4-C10-alkane carboxylic acid)amine, 1,4-piperazine-di(C1-C10-alkane carboxylic acid), and a process for producing these filaments, their use for the production of fibers and flat products, and fibres and flat products made of these filaments.
