摘要

Total 100% by weight comprising the transparent blends or alloys: (A) 1 to 99 wt. amorphous copolymers with one or more configuration or have a% crystallinity range of from semi-crystalline; Including to: (A1) at least one cycloaliphatic unit of the amide as a unit; (A2) flexibility ether unit; (B) 99 to 1% by weight of polymer selected from one or more configurations of: (Ba) half amide containing units (Ba1) and the ether units (Ba2) crystalline copolyamide, (Bb) there is no semi-crystalline ether units a polyamide or copolyamide, (Bc) do not have an amorphous or low crystalline polyamide or polyether units transparent copolyamide, and the polyamide or copolyamide based alloys; And (C) the (A) and 0 to 50% by weight of the polyamide used in addition to (B), co-polyamide, at least one copolyamide containing units of the ether or the polyamide or copolyamide base alloy. The resulting blends or alloys having a high transparency, such as more than 50% of the transmittance at 560 nm for plates with a thickness of 2 mm.
