Gel permeation chromatography (GPC), Fourier transform infrared spectrometer (FT-IR), X-ray diffraction (XRD) were adopted to characterize and analyze the degraded products.
The FT-IR magneto-optical spectrometer with high optical transportation efficiency was developed by adopting a novel design. In the present paper, its construction and characteristics are described.
