What is Gel permeation chromatography—Fourier transform infrared study of some synthetic polymers about?

A high-temperature gel permeation chromatography-Fourier transform infrared (GPC-FT-IR) system was developed to characterize commercially available polyethylene. High-temperature transfer tubing was used to connect the high-temperature flow cell of an FT-IR spectrophotometer and a high-temperature GPC system. The GPC-$T-IR system was calibrated to determine the molecular weight distribution (MWD) and the short-chain branching (SCB) for high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE). The MWD and SCB of a commercial LLDPE determined using the present GPC-FT-IR system compared favourably with those measured with a solvent gradient elution fractionation technique where 13C NMR spectrometry was employed to determine the SCB for the same PE.
