Abstract

Summary: This disseration investigates the chemical and physical properties of 11 samples of shellacs that have been derived from the Lac insect's resinous secretion. These samples were examined using Fourier Transform Infrared Spectroscopy (FTIR), fluorescence Spectroscopy, Ultraviolet-Visible Spectroscopy, and Gas Chromatography Mass Spectrometry (GC-MS) to investigate components. The commotional program, Hyperchem was used to compute properties of component models which would give rise to the observed physical properties using ab-initio and semi-empirical calculations. Samples were heated in order to model the aging process and were compared with the original samples.
