PRESSED FILM TECHNIQUE AND INFRARED SPECTRA CATALOG FOR IDENTIFICATION OF THEMOPLASTICS.

Abstract

A modified compression molding technique for obtaining film of thermoplastics for infrared examination is described. Small specimens of thermoplastic materials were heated to their softening points and pressed into thin, transparent film from which were obtained infrared spectra. The advantages and limitations of this technique are discussed. A pressed film spectra catalog was compiled to be used as a reference for identifying unknown samples. This catalog includes spectra of most of the commercially important thermoplastics, including the newer ones. (Author)
