Embodiment 1

[0029] 2.68g (10mmol) bisphenol Z (1,1'-bis(4-hydroxyphenyl)cyclohexane), 3.36g (10mmol) bisphenol AF (2,2'-bis(4-hydroxyphenyl) Hexafluoropropane) was dissolved in 100 mL of sodium hydroxide aqueous solution with a mass concentration of 5% under stirring. After adding 0.23g (1mmol) benzyltriethylammonium chloride and 0.03mL (0.2mmol) triethylamine at 25°C, add dropwise a solution of triphosgene in dichloromethane [5.96g (20.1mmol) triphosgene In 150mL of dichloromethane], after fully stirring for half an hour, the temperature was raised to 35°C for polycondensation reaction for 3 hours. After the reaction, the water phase was separated with a separatory funnel to obtain a dichloromethane solution containing bisphenol Z-bisphenol AF copolymer polycarbonate. Synthetic route such as figure 1 Shown.

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 copolymer polycarbonate binding resin, and belongs to the technical field of polymer binding resin preparation. Background technique [0002] Polycarbonate is a kind of functional resin, among which the most common is bisphenol A polycarbonate, which has colorless and transparent, good impact resistance and good adhesion, making it in the fields of organic optoelectronics, information display and recording There are 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 small molecule compounds with carrier transport functions with bisphenol A polycarbonate. Dissolve in a solvent to form a solution with a certain viscosity, and then form a functional film through solution processing me...
