    摘要： The present invention relates to polyamide oligomers with linear or branched chain structure with a number average molar mass of 800 to 5000 g/mol, with basic end groups which are at least partially NH2 end groups and carboxyl end groups, produced by condensation of polyamide-forming monomers, the concentration of NH2 end groups being at most 300 mmol/kg and in that these end groups are present in excess in a ratio to the carboxyl end groups.

    摘要： The invention relates to a polymer mixture of partially crystalline aliphatic polyamides and partially aromatic polyamides, the proportion of aliphatic polyamides being more than 50% by weight and the quantitative ratio of the aliphatic carbon atoms to amide bonds in the aliphatic polyamides being in the range of 8:1 to 12:1 and the partially aromatic polyamides, which are present in deficit, having, in addition to hexamethyleneterephthalamide (6T) units, further partially aromatic and/or aliphatic amide units and being predominantly partially crystalline. The invention relates furthermore to the use of polymer mixtures of this type for various application fields, in particular for express couplings or connectors for fuel lines.

    摘要： The present invention relates to thermoplastic polyamide moulding compositions which contain at least one copolyamide with at least 20% by weight polyamide 12 components and at least one aprotic compound selected from the group of N-alkylated, cyclic carboxylic acid amides with 5 to 7 ring elements and/or of urea derivatives, the alkyl rests of which are linear at the nitrogen or which form a linking of the two N-atoms, and a process for production of the moulding compositions. The thermoplastic polyamide moulding compositions are distinguished by the fact that no solid deposits are formed during thermoplastic conversion.
