This paper documents a new polyolefin characterization technique, high-temperature thermal gradient interaction chromatography (HT-TGIC or TGIC), to quantify comonomer distribution. A set of homogeneous ethylene−octene homopolymers are used with a commercially available column having a graphitic sub...
