Abstract
(EN)
The present invention provides: a film which contains a polymer having a weight average molecular weight that is not less than Mf1 represented by formula (1), and which is configured such that the polymer has a glass transition temperature of 60°C or more and the content of fine particles having a particle diameter of from 10 nm to 10 μm (inclusive) in the film is 40 parts by mass or less relative to 100 parts by mass of the polymer; a method for producing this film; and an optical device and a foldable device, each of which is provided with this film. (1): Mf1 = 6.60 × 10(4 + Me/11400) In formula (1), Me represents the molecular weight between entanglement points of the polymer.
(FR)
La présente invention concerne : un film qui contient un polymère ayant un poids moléculaire moyen en poids qui n'est pas inférieur à Mf1 représenté par la formule (1), et qui est conçu de telle sorte que le polymère a une température de transition vitreuse de 60 °C ou plus et la teneur en fines particules ayant un diamètre de particule de 10 nm à 10 µm (inclus) dans le film est de 40 parties en masse ou moins par rapport à 100 parties en masse du polymère ; un procédé de production de ce film ; et un dispositif optique et un dispositif pliable, chacun d'eux étant pourvu de ce film. (1) : Mf1 = 6,60 × 10(4 + Me/11400) Dans la formule (1), Me représente le poids moléculaire entre les points d'enchevêtrement du polymère.
(JA)
