| titleOfInvention | Blends and alloys based on an amorphous to semicrystalline copolymer, comprising amide units and comprising ether units, wherein these materials have improved optical properties |
| abstract | A transparent blend or mixture comprising, by weight, the total being 100%: (A) 1 to 99% of at least one copolymer component: being amorphous or having a crystallinity of up to half crystallinity; and - comprising: (A1) amide units among which is at least one cycloaliphatic unit; (A2) flexible ether patterns; (B) 99 to 1% of at least one polymeric component chosen from: (Ba) semi-crystalline copolyamides with amide (Ba1) units and with ether units (Ba2), (Bb) semi-crystalline polyamides or copolyamides without ether units, (Bc) transparent polyamides or copolyamides, without ether units, being amorphous or weakly crystalline and alloys based on such polyamides or copolyamides; and (C) 0 to 50% by weight of at least one polyamide, copolyamide, copolyamide with ether or alloy units based on such polyamides or copolyamides other than those used in (A) and (B) above. The resulting mixture or alloy has a high transparency such that the transmittance at 560 nm on a 2 mm thick plate is greater than 50%. |
