ABSTRACT:
A method for distinguishing a kind of plastic materials, by preparing a test piece of a plastic material; measuring an infrared spectrum of the test piece by attenuated total reflection spectroscopy; and comparing the obtained infrared spectrum with an infrared spectrum of a known plastic. The test piece has a section. The infrared spectrum of the test piece is measured by bringing the crystal for attenuated total reflection spectroscopy into contact with the section of the test piece.
