Abstract
SummaryHigh‐temperature thermal gradient interaction chromatography (HT‐TGIC) can be used to measure the chemical composition distribution (CCD) of semi‐crystalline and amorphous polyolefins. HT‐TGIC extends the range of polyolefin chemical compositions that can be measured today with crystallization‐based techniques. Hypercarb® columns packed with porous graphitic carbon are commonly used as the stationary phase in HT‐TGIC fractionation. We used a set of ethylene/1‐octene copolymers having different comonomer fractions (up to 25% of 1‐octene) and approximately the same molecular weight average to investigate how commercial Hypercarb® columns with distinct lengths and particle sizes affected HT‐TGIC fractionation. Binary copolymer blends were also analyzed to study how different blend compositions affected HT‐TGIC peak positions and shapes.
