摘要
升温淋洗分级技术是根据结晶性聚合物的结晶度进行分级和表征的一项分析和制备技术 ,在聚烯烃非均匀性的表征和窄组成分布样品的制备中有重要应用。本文主要介绍升温淋洗分级原理、热力学模型、装置技术特点。
Temperature rising elution fractionation(TREF) is an analytical and preparative technology for fractionation and characterization of polymers based on crystallinity. TREF has gained popularity for characterization of heterogeneity of polyelofins and preparation of polyelofins fractions with homogeneous structure. This review covers the principle\,thermodynamic model\,analytical method and applications in polyethylene research field over the past few years.\;
