Abstract

A method to analyze additives in a polyester resin has been studied by utilizing a centrifuge and a thin layer chromatography. Identification of the separated organic and inorganic compounds were carried out by spectrophotometers, such as NMR, UV-VIS, IR and XRD. For the polyester resin studied in this research contained organic and inorganic compounds which were found to be a dimer form of 2-phenylbenzoazole and an anatase form of $TiO_2$, respectively.
