摘要
对近年来半芳香族聚酯(聚对苯二甲酸乙二醇酯、聚对苯二甲酸丙二醇酯、聚对苯二甲酸丁二醇酯)中环状低聚物的提取方法和分离手段、结构表征、热性能、形成机理及环状低聚物对聚酯纤维纺丝、染色和性能带来的影响等方面的研究进展进行了综述。针对我国近年来快速发展的生物基聚酯,为实现稳定化、连续化生产,提出如何解决环状低聚物带来的关键问题。指出从根源抑制环状低聚物的生成或去除以及解决低聚物对纤维产品带来的问题是当今及以后的重点研究方向。
The research progress of the extraction and separation technologies,structure characterization,thermal property and formation mechanism for cyclic oligomers in semiaromatic polyesters,including polyethylene terephthalate,polytrimethylene terephthalate,polybutylene terephthalate,was reviewed in the latest years,as were the effects of cyclic oligomers on the spinning and dyeing processes and properties of polyester fibers.In view of the rapid development of bio-based polyesters in China in the latest years,in order to realize the stable and continuous production,the solution to the key problems of cyclic oligomers was put forward.It was pointed out that the current and future research should be focused on inhibiting the formation or removal of cyclic oligomers and solving the problems caused by oligomers on fiber products.
