| abstract |
The present invention provides a molding material having a polyarylene sulfide skeleton, which is particularly excellent in moldability in a solution state, and an optical member using the same. A weight-average molecular weight of 21,000 or more, a number-average molecular weight of 7000 or more, obtained through an oxidative polymerization step using an ortho- or paraquinone-based oxidant, having a repeating unit represented by formula (I), and A molding material having a dispersity of 3.0 or more. An optical member formed through a process of removing the solvent from a solution obtained by dissolving the molding material in a solvent. [Selection figure] None |
