Abstract

ABSTRACT Four polyether ester plasticizers containing both ester groups and ether bonds were synthesized using 1,4‐butanediol, adipic acid, and alkyl ether alcohols as raw materials. By varying the type of end‐capping alcohol ether, the following plasticizers were prepared: poly (butylene adipate dibutyl ether) (PBADBE), poly (butylene adipate butyl ether) (PBABE), poly (butylene adipate dimethyl ether) (PBADME), and poly (butylene adipate methyl ether) (PBAME). These plasticizers were characterized by Fourier transform infrared (FTIR) spectroscopy, proton nuclear magnetic resonance spectroscopy ( 1 H‐NMR), and thermogravimetric (TG) analysis. Furthermore, their differences in cold resistance, heat resistance, and physical‐mechanical properties in hydrogenated nitrile‐butadiene rubber (HNBR) were investigated. The results showed that among the rubber compounds containing the four polyether‐ester plasticizers, the compound with PBADME demonstrated superior heat resistance and low‐temperature performance. Specifically, the PBADME‐containing compound exhibited a TR 10 temperature of −39.9°C and a brittleness temperature of −54°C. This significantly broadened the operating temperature range of the plasticizer, making it suitable for applications requiring both high‐temperature and low‐temperature performance.

聚醚酯增塑剂的合成及其在氢化丁腈橡胶中的应用性能

摘要以1,4 -丁二醇、己二酸和烷基醚醇为原料，合成了4种同时含有酯基和醚键的聚醚酯增塑剂。通过改变端盖醇醚的类型，制备了以下增塑剂：聚己二酸丁烯二丁基醚（PBADBE）、聚己二酸丁烯丁基醚（PBABE）、聚己二酸丁烯二甲醚（PBADME）和聚己二酸丁烯甲基醚（PBAME）。这些增塑剂通过傅里叶变换红外光谱（FTIR）、质子核磁共振光谱（1h‐NMR）和热重（TG）分析进行了表征。进一步研究了它们在氢化丁腈橡胶（HNBR）中的耐寒性、耐热性和物理力学性能的差异。结果表明，在含四种聚醚酯增塑剂的橡胶化合物中，含PBADME的橡胶化合物具有较好的耐热性和低温性能。具体来说，含PBADME的化合物的TR - 10温度为- 39.9°C，脆性温度为- 54°C。这大大拓宽了增塑剂的工作温度范围，使其适用于需要高温和低温性能的应用。

期刊介绍： Polymers for Advanced Technologies is published in response to recent significant changes in the patterns of materials research and development. Worldwide attention has been focused on the critical importance of materials in the creation of new devices and systems. It is now recognized that materials are often the limiting factor in bringing a new technical concept to fruition and that polymers are often the materials of choice in these demanding applications. A significant portion of the polymer research ongoing in the world is directly or indirectly related to the solution of complex, interdisciplinary problems whose successful resolution is necessary for achievement of broad system objectives. Polymers for Advanced Technologies is focused to the interest of scientists and engineers from academia and industry who are participating in these new areas of polymer research and development. It is the intent of this journal to impact the polymer related advanced technologies to meet the challenge of the twenty-first century. Polymers for Advanced Technologies aims at encouraging innovation, invention, imagination and creativity by providing a broad interdisciplinary platform for the presentation of new research and development concepts, theories and results which reflect the changing image and pace of modern polymer science and technology. Polymers for Advanced Technologies aims at becoming the central organ of the new multi-disciplinary polymer oriented materials science of the highest scientific standards. It will publish original research papers on finished studies; communications limited to five typewritten pages plus three illustrations, containing experimental details; review articles of up to 40 pages; letters to the editor and book reviews. Review articles will normally be published by invitation. The Editor-in-Chief welcomes suggestions for reviews.
