High-temperature thermal gradient interaction chromatography (HT-TGIC) can be used to measure the chemical composition distribution of ethylene/α-olefin copolymers using a column packed with porous graphitic carbon. It is generally assumed that polymer molecular weight plays a secondary role in HT-TGIC fractionation, but this assumption is incorrect for lower-molecular-weight polymers. In this article, we developed a general calibration curve to quantify the effect of polymer molecular weight, α-olefin fraction, and type (1-hexene, 1-octene, and 1-decene) on HT-TGIC peak temperatures and discussed its implications on converting HT-TGIC profiles into chemical composition distributions.
