摘要:
A film which comprises a layer composed of a moulding composition composed of a semicrystalline polyamide whose enthalpy of fusion is at least 8 J/g is used for production of a composite part with a substrate composed of a moulding composition composed of a substantially amorphous polyamide whose enthalpy of fusion is less than 8 J/g.
摘要:
A composition, containing at least 50% by weight of a polyamide fraction which comprises: a) from 50 to 95 parts by weight of a polyamide having as copolymerized units bis(4-aminocyclohexyl)methane (PACM) and a linear dicarboxylic acid having from 8 to 18 C atoms; and b) from 50 to 5 parts by weight of a linear aliphatic polyamide having an average of from 8 to 12 C atoms in the monomer units, where the sum of the parts by weight of a) and b) is 100 is provided. The composition can be processed to give a moulded article having high transparency, high toughness and high resistance to chemicals, to solvents and to stress cracking.
