Polyolefin Characterization by High Temperature Solvent Gradient Interaction Chromatography: Transitioning Away from Chlorinated Desorption Promoting Solvents

Abstract High temperature solvent gradient interaction chromatography (HT-SGIC) has been established as a cornerstone technique to elucidate the chemical composition (CC) and underlying chemical composition distribution (CCD). In HT-SGIC, the adsorption (adsorlis) and desorption...
