Partially aromatic polyamides with a reduced triamine content

Partially aromatic copolyamides containing, as essential components, A1) 40-90% by weight of units derived from terephthalic acid and hexamethylenediamine, A2) 0-50% by weight of units derived from epsilon -caprolactam and A3) 0-60% by weight of units derived from adipic acid and hexamethylenediamin...

More Information
Summary:Partially aromatic copolyamides containing, as essential components, A1) 40-90% by weight of units derived from terephthalic acid and hexamethylenediamine, A2) 0-50% by weight of units derived from epsilon -caprolactam and A3) 0-60% by weight of units derived from adipic acid and hexamethylenediamine, components A2) and/or A3) in total making up at least 10% by weight of the total amount of units, and the copolyamides having a triamine content of less than 0.5% by weight, are used in impact-modified compositions and mouldings.
