The structure of acrylonitrile butadiene styrene copolymer (hereinafter referred to as ABS resin) was explored. The derivative mid infrared (MIR) spectroscopy studies on ABS resin structures (including first-order derivative MIR spectroscopy, second-order derivative MIR spectroscopy, third-order derivative MIR spectroscopy, and fourth-order derivative MIR spectroscopy,) as well as second-order derivative MIR light studies under different smoothing conditions (including 5 smoothing points, 9 smoothing points, 13 smoothing points, 19 smoothing points, 25 smoothing points, 37 smoothing points, 49 smoothing points, and 149 smoothing points) were conducted. Experiments have found that the infrared absorption modes of functional groups in ABS resin structures include: ν■, ν■, ν■, ν■, ν■, ν■, δ■, γ■, γ■ and γ■. Under the condition of 5 smooth points, the second derivative MIR spectrum of functional groups in ABS resin structure can provide richer spectral information. Derivative MIR spectroscopy can quickly conduct structural studies on ABS resin.
