异山梨醇型聚碳酸酯的制备方法及性能调控研究进展

Progress on preparation methods and performance regulation of isosorbide based polycarbonate

摘要:

以石油为基础原料的双酚A型聚碳酸酯(BPA-PC)因双酚A具有不可再生和雌激素效应等问题导致其在食品包装等领域的应用受到限制。近年来，寻求一种无毒无害、可替代双酚A制备聚碳酸酯的单体已成为业内的研究热点。异山梨醇(IS)作为生物基可再生单体、无毒无害，是目前最有希望代替双酚A合成聚碳酸酯的关键原料，用其合成的异山梨醇型聚碳酸酯(IS-PC)具有无毒及优异的光学性能、耐划伤性、热稳定性、生物降解性和生物相容性等，已在包装、汽车、电子电器、生物医学等领域显示出良好的应用前景。本文对异山梨醇型聚碳酸酯（IS-PC）的制备方法及性能调控进行了综述，详细对熔融酯交换法制备异山梨醇型聚碳酸酯（IS-PC）进行了阐述，重点对调控异山梨醇型聚碳酸酯（IS-PC）性能的方法进行了分类归纳，并对异山梨醇型聚碳酸酯的研究方向进行了展望。

Abstract:

Bisphenol A based polycarbonate (BPA-PC) by petroleum as raw materials is limited in the application of food packaging and other fields due to the non-renewable and estrogenic effects of bisphenol A. In recent years, Isosorbide (IS), as a bio-based renewable monomer that is non-toxic and harmless, is currently the most promising key raw material for replacing bisphenol A in the synthesis of polycarbonates. And the isosorbide based polycarbonate (IS-PC) has non-toxicity, excellent optical properties, scratch resistance, thermal stability, biodegradability and biocompatibility, which has shown good application prospects in packaging, automobiles, electronics, biomedicine and other fields. This article reviews the preparation methods and performance regulation of IS-PC, focusing on the preparation of IS-PC by melt transesterificationthe, summarizing the methods of regulating the performance of isosorbide polycarbonate ( IS-PC ) and prospects for the research direction of IS-PC.
