Analysis of Acrylonitrile-Butadiene-Styrene (ABS) Plastics by Infrared Spectroscopy

Part of the Developments in Applied Spectroscopy book series (DAIS, volume 7b)


ABS plastics are heterogeneous blends of styrene-acrylonitrile copolymers and modified polybutadiene rubbers. The degree of toughness of these versatile thermoplastics is almost entirely a function of the type and character of the rubber. The complex structure of ABS resins and the many additives used to improve the finished plastic make it difficult to analyze these materials without first breaking them down into their component parts. Infrared spectroscopy, however, allows a rapid method for comparing commercial resins. In addition, infrared calibration curves are extremely useful in analyzing the composition of ABS plastics. Analyses based on this technique provide information on which predictions about the physical properties of the molded plastic can be made.
