摘要

本文采用熔融酯交换反应，以碳酸二苯酯（DPC）、9,9'-双[6-(2-羟基乙氧基)萘基]氟（BNEF）、2,2'-双(2-羟基乙氧基)-1,1'-联萘（BHEBN）为聚合单体，制备了一系列不同摩尔投料比的共聚碳酸酯。研究发现，当 BHEBN 和 BNEF 的摩尔比为 6:4 时，共聚物的综合性能更好。共聚物的 Mn 为 23000 Mn，Mw 为 40700，PDI 为 1.77。玻璃化温度为 147.6℃，初始热分解温度（Td,5%）为 338.9℃，折射率为 1.6753，阿贝数为 18.7，透光率为 86.23%。

Synthesis and optical properties of co-polycarbonate containing Cardo structure and binaphthalene structure

In this paper, molten transesterification was used with diphenyl carbonate (DPC), 9,9'-bis[6-(2-hydroxyethoxy)naphthyl]fluorine (BNEF), 2,2'-bis(2-hydroxyethoxy)-1,1'-binaphthalene (BHEBN) were used as the polymeric monomers to prepare a series of co-polycarbonates with different molar feeding ratios. It is found that when the molar ratio of BHEBN and BNEF is 6:4, the copolymer has more comprehensive properties. The Mn of the copolymer is 23000 Mn, the Mw is 40700, and the PDI is 1.77. The glass transition temperature is 147.6℃, the initial thermal decomposition temperature (T_d,5%) is 338.9℃, the refractive index is 1.6753, the Abbe number is 18.7, and the light transmittance is 86.23%.

期刊介绍： Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology. As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology, including: polymer synthesis; polymer reactions; polymerization kinetics; polymer physics; morphology; structure-property relationships; polymer analysis and characterization; physical and mechanical properties; electrical and optical properties; polymer processing and rheology; application of polymers; supramolecular science of polymers; polymer composites.
