A process for producing an activated monomer composition comprising at least one lactam and/or lactone, one catalyst, and one activator permits storage of the resultant monomer composition, since this is stable with respect to polymerization. Said monomer composition is used inter alia in producing a polyamide molding via ring-opening, anionic polymerization.

Use of polyamides that are resistant to corrosion and stress cracking

Thermoplastic molding compositions comprising A) from 10 to 99% by weight of at least one thermoplastic polyamide, B) from 0.01 to 30% by weight of at least one highly branched or hyperbranched polyetheramine, C) from 0 to 70% by weight of further added materials, where the total of the percentages by weight of components A) to C) is 100%; the use of polyetheramines for improving the flowability and/or thermal stability of polyamides; and to the use of the molding compositions for the production of fibers, of foils, or of moldings of any type, and also to the resultant fibers, foils, or moldings.

The present invention relates to a process for the preparation of R- and S-lipoic acid and R- and S-dihydrolipoic acid comprising (a) reaction of 

Process for the preparation of lipoic acid and dihydrolipoic acid

The invention relates to a process for purifying lipoic acid, which comprises adding to a solution of lipoic acid at least 0.1 times the amount of an adsorbent, based on the mass of lipoic acid to be purified, and subsequently removing the adsorbent. It is possible in this way to provide racemic or nonracemic lipoic acid with an oligomer content below 1% by weight, for example from 0.1 to 1% by weight.

Flame-proofed polyester molding materials

The invention relates to a method for the continuous production of polybutylene terephthalate from terephthal acid and 1,4-butane diole, comprising the following stages: a) direct esterification of terephthal acid with 1,4-butane diole in a reactor cascade of at least two reactors b) pre-condensation of the esterification product obtained in stage a), c) polycondensation of the pre-condensate obtained in stage b), whereby the temperature of the reactor cascade in stage a) is progressively decreased during its operation.
