Polyamide mixtures (blends) or alloys having improved transparency, chemical resistance and slight natural color, as well as a process improving the melting capacity and homogeneity of blends of polyamide according to formula (I) and partly crystalline polymers according to formula (II). Transparent polyamide blends are obtained which exhibit improved properties with respect to transparency, color, and chemical resistance, in particular stress cracking resistance against isopropanol, without resulting losses in the mechanical properties. At the same time it was possible to distinctly raise the throughput during extrusion while maintaining optimum transparency. |
