Abstract

Polyarylates containing phthalazinone moieties are synthesized by interfacial polymerization of 2,4-(4-hydroxyphenyl)-2,3-phthalazin-1-one with isophthaloyl dichloride (IPC) and terephthaloyl dichloride (TPC). The effects of organic solvents and phase transfer catalysts (PTC) on the intrinsic viscosity (η int ) are systematically investigated for polymers with η int up to 1.52 dL g−1. The polyarylate has a high η int with 1,2-dichloroethane and cetyltrimethylammonium bromide used as the organic phase solvent and PTC. It is found that polyarylates prepared from BPPZ with IPC and TPC have excellent thermal resistance, with glass transition temperatures of 292 and 337°C, respectively. The polyarylates exhibit excellent thermal stability with 5% mass-loss temperature above 469°C in both N2 and air, and residual mass ratios at 800°C in N2 and air above 54.1% and 4.0%, respectively.

含有具有优异耐热性的邻苯二甲嗪酮部分的聚丙烯酸酯

通过2，4-（4-羟基苯基）-2，3-邻苯二甲嗪-1-酮与间苯二甲酰二氯（IPC）和对苯二甲酰基二氯（TPC）的界面聚合，合成了含有邻苯二氮酮部分的聚丙烯酸酯。系统地研究了有机溶剂和相转移催化剂（PTC）对ηint高达1.52dL g−1的聚合物特性粘度（ηint）的影响。以1,2-二氯乙烷和十六烷基三甲基溴化铵为有机相溶剂和PTC，得到了具有高ηint的聚丙烯酸酯。研究发现，由BPPZ与IPC和TPC制备的聚丙烯酸酯具有优异的耐热性，玻璃化转变温度分别为292和337°C。聚丙烯酸酯在氮气和空气中均表现出优异的热稳定性，在469°C以上的温度下质量损失为5%，在800°C的N2和空气中残余质量比分别高于54.1%和4.0%。

期刊介绍： Health Services Management Research (HSMR) is an authoritative international peer-reviewed journal which publishes theoretically and empirically rigorous research on questions of enduring interest to health-care organizations and systems throughout the world. Examining the real issues confronting health services management, it provides an independent view and cutting edge evidence-based research to guide policy-making and management decision-making. HSMR aims to be a forum serving an international community of academics and researchers on the one hand and healthcare managers, executives, policymakers and clinicians and all health professionals on the other. HSMR wants to make a substantial contribution to both research and managerial practice, with particular emphasis placed on publishing studies which offer actionable findings and on promoting knowledge mobilisation toward theoretical advances. All papers are expected to be of interest and relevance to an international audience. HSMR aims at enhance communication between academics and practitioners concerned with developing, implementing, and analysing health management issues, reforms and innovations primarily in European health systems and in all countries with developed health systems. Papers can report research undertaken in a single country, but they need to locate and explain their findings in an international context, and in international literature.
