Abstract
Thermoplastic molding compositions including a semicrystalline polyamide a) and an amorphous copolyamide b), the latter containing dimerized fatty acid as one monomer building block. Optionally, a compatibility agent and other additives are also included. The molding compounds having high stiffness up to at least 100.degree. C. are produced by melt-mixing components a) and b), and optionally a compatibilizer, and are used for making molded parts which are outstanding in their thermal properties, high solvent resistance, and resistance to stress corrosion.
