Beschreibung
Zusammenfassung:	Disclosed are a polydisulfide material having excellent optical properties and a preparation method therefor, which belong to the field of macromolecular materials. The polydisulfide is a polydisulfide formed by the copolymerization of episulfide alkane and elemental sulfur under the action of a catalyst. The content of disulfide segments in a main chain of the polydisulfide is 95-99%. The polydisulfide material provided in the present invention has the advantages of having a high refractive index, a high Abbe number and high light transmittance. Un matériau de polydisulfure ayant d'excellentes propriétés optiques et son procédé de préparation, qui appartient au domaine des matériaux macromoléculaires, sont divulgués. Le polydisulfure est un polydisulfure formé par la copolymérisation d'épisulfure alcane et de soufre élémentaire sous l'action d'un catalyseur. La teneur des segments disulfures dans une chaîne principale du polydisulfure est de 95 à 99 %. Le matériau de polydisulfure fourni par la présente inve
