Evaluation of Annealed Poly(ethylene Terephthalate) Structures by Gas Chromatography

Solvent-crystallized, ground PET fibers were used in a gas chromatographic column as the stationary phase and subjected in situ to increasingly severe thermal treatment. After each treatment, an homologous series of hydrocarbons was passed through the column as molecular probes. After an initial red...

Description
Summary:Solvent-crystallized, ground PET fibers were used in a gas chromatographic column as the stationary phase and subjected in situ to increasingly severe thermal treatment. After each treatment, an homologous series of hydrocarbons was passed through the column as molecular probes. After an initial reduction in surface sonption that was produced by heat treatment at 145°C, no further change was effected by heat, up to 175°C. Above 175°C, surface sorption decreased, while internal bulk partitioning increased, indicating marked internal changes of structure.
