Abstract
Matière filamenteuse optique comportant une âme formée d'une matière polymère thermoplastique optiquement transparente, et une gaine polymère transparente sensiblement amorphe ayant un indice de réfraction plus faible. La gaine est séparée d'une enveloppe protectrice par un écran thermique qui protège thermiquement la matière filamenteuse optique pendant lextrusion et l'application de l'enveloppe. Application à l'industrie optique.
