Properties of materials as determined by inverse gas chromatography

Abstract

The application of inverse gas chromatography (IGC) in the determination of the physicochemical properties of various materials is presented and discussed. The special attention is focused on the determination of solubility parameters.

Lewis acid/base character and crystallisation properties of poly(butylene terephthalate)

“…The apolar probes used were n-heptane, n-octane, n-nonane, n-decane, and the polar probes tetrahydrofuran (THF, basic probe), the amphoteric probes acetone (Acet) and diethyl ether (DEE), and the acidic probes chloroform (TCM) and dichloromethane (DCM). In Table 2 are summarised relevant properties of the probe molecules mentioned [17][18][19][20][21]. The chemicals used as probe molecules were obtained from Sigma-Aldrich Ltd., Poole, UK.…”

“…Due to its applicability in determining the surface properties of solids in varied forms such as films, fibres and powders of both crystalline and amorphous structures, IGC has been extensively used for surface characterisation. The applicability of IGC in measurements of physicochemical properties of various materials has been thoroughly described in the literature [15][16][17][18]. Data obtained from IGC experiments may, in favourable cases, correlate directly with observed performance criteria, such as colour development, gloss, rheological properties, adhesion and mechanical properties [19][20][21].…”
