| abstract |
The invention relates to a stretched molded article comprising a polymer A and a compound B, wherein the polymer A is a polyamide or a polyolefin and is at least partially oriented and comprises a crystalline phase and a non-crystalline phase, wherein the mass of compound B is from 0.25 to 10 mass% relative to the mass of polymer A, and wherein the compound B has a refractive index (n B ) higher than the isotropic refractive index of polymer A (n A ). The invention further relates to a process for manufacturing such stretch molded article, the use of such stretch molded articles and a product comprising such stretch molded article. |
