    摘要： A process for crosslinking polyamides by reacting a compound of the general formula R1R2C═CR3—X in which R1, R2 and R3 are each independently hydrogen or an organic radical with a lactam A at a temperature of (−30) to 150° C., and then reacting with a lactam B, a catalyst and an activator at a temperature of 40 to 240° C.

    摘要： The invention relates to thermoplastic molding compositions comprising: A) from 10 to 89% by weight of a polyethylene terephthalate or polybutylene terephthalate, B) from 10 to 60% by weight of a fibrous reinforcing material with a fiber length of from 2 to 24 mm, C) from 1 to 20% by weight of at least one polyester based on aliphatic and aromatic dicarboxylic acids and on an aliphatic dihydroxy compound, D) from 0 to 40% by weight of further additives, where the entirety of components A) to D) is 100%. The invention further relates to the use of thermoplastic molding compositions for producing long-fiber-reinforced pellets and to the pellets thus obtainable. The invention further relates to the use of pellets of this type for producing moldings of any type with good notched impact resistance, and to the resultant moldings.

    摘要： Polyamides based on dicarboxylic acids and on diamines are produced in a batch process by 1) feeding the entire amount of monomer composed of dicarboxylic acids, of diamines, and, if appropriate, of further polyamide-forming monomers, in the desired stoichiometry, in a closed stirred-tank reactor, 2) heating the monomer mixture in the stirred-tank reactor, with stirring, and with setting of a certain pressure, to a desired reaction temperature for the production of a prepolymer, 3) if appropriate, completely or partially depressurizing the reaction mixture from stage 2), 4) if appropriate, carrying out further thermal treatment of the reaction mixture from stage 2) or 3), and 5) reacting the reaction mixture from stage 2), 3), or 4) in the melt in a vented extruder for further increase of the molecular weight, with discharge of water vapor, and without use of additional polyamide-forming monomers or of polyamides.

    摘要： For the anionic polymerization of lactams: (a) (i) a catalyst capable of creating a lactamate and (ii) a regulator chosen from amides of formula R1-NH—CO-R2, in which R1 can be substituted by an R3-CO—NH— or R3-0— radical and in which R1, R2 and R3 denote an aryl, alkyl or cycloalkyl radical, are dissolved in the molten lactam, (a1) the solution from stage (a) is cooled, optionally to the solid state in a form which can be divided, (a2) the product from stage (a1) is optionally reheated to a temperature below the polymerization temperature of the lactam, (a3) optionally, the product from stage (a1) is reheated and is maintained at a temperature between the melting temperature of the lactam and 15° C. above, and (b) the produce from any one of stages (a1), (a2) or (a3) is introduced into a mixing device or mold and is then heated to a temperature sufficient to obtain the bulk polymerization of the lactam.
