Abstract: PCT No. PCT/EP94/01998 Sec. 371 Date Dec. 28, 1995 Sec. 102(e) Date Dec. 28, 1995 PCT Filed Jun. 20, 1994 PCT Pub. No. WO95/01389 PCT Pub. Date Jan. 12, 1995A process for the continuous production of polyamides from a mixture of at least one lactam and water and, if required, other monomer units and/or conventional additives and fillers under polyamide-forming conditions, where the mixture of the starting materials is heated in liquid phase in a first reaction zone until a conversion of at least 70% is reached, and undergoes adiabatic decompression and further polymerization in another reaction zone, wherein, in the first reaction zone, 0.5-7% by weight of water are employed, the temperature is increased to the range from 220 DEG to 310 DEG C., and polymerization is carried out until a conversion of at least 85% is reached and, in the second reaction zone, after the decompression further polymerization is carried out in the range from 215 DEG to 300 DEG C. without heat input.

Abstract: A process is claimed for the prodn. of linear polyamides (I) from 4-15C diamines (II) and 4-15C dicarboxylic acids (III) by solid-phase condensation of the corresp. salts in the presence of phosphorus cpds. (IV) as catalysts; the process comprises: (a) reaction of (II) with (III) in a liq. medium at elevated temp., with addn. of (IV) to give a soln., suspension or dispersion of the salt, (b) removing the liq. medium to give solid salt contg. (IV), (c) heating the salt under inert gas at a temp. between 130-5 deg.C below the m.pt. of the salt to give a precondensate with total end-gp. equiv. wt. 5000-12000 m-equiv./kg and (d) further condensation to the required deg. at a temp. above that used in stage (c).
