Abstract

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.
