Abstract

The invention relates to bisphenol Z-bisphenol AF copolymer polycarbonate adhesive resin as well as a preparation method and application thereof. Bisphenol Z and bisphenol AF are copolymerized in a certain proportion to prepare binary copolymer polycarbonate; and according to needs of different solubility, the bisphenol Z, the bisphenol AF and triphosgene in different proportions are copolymerized to prepare the bisphenol Z-bisphenol AF copolymer polycarbonate. According to the bisphenol Z-bisphenol AF copolymer polycarbonate, the binary copolymer polycarbonate prepared by copolymerizing the bisphenol Z, the bisphenol AF and the triphosgene is proper in molecular weight distribution, is relatively good in solubility, and is relatively low in cost; and the binary copolymer polycarbonate is used as adhesive resin of a carrier transmission material for preparing a carrier transmission layer of an organic optical conductor.

Description

technical field [0001] The invention relates to the preparation and application of a novel bisphenol Z and bisphenol AF polymerization to prepare a binary copolycarbonate binder resin, and belongs to the technical field of polymer binder resin preparation. Background technique [0002] Polycarbonate is a functional resin, the most common of which is bisphenol A polycarbonate, which has colorless transparency, good impact resistance and good adhesion, making it widely used in the fields of organic optoelectronics, information display and recording. have important applications. Functional films such as organic information recording and display usually use bisphenol A polycarbonate as a binder and film-forming agent. The general process is to combine a small molecule compound with carrier transport function with bisphenol A polycarbonate Dissolve in a solvent to form a solution with a certain viscosity, and then form a functional film by solution processing (such as spin coati...
