Gc. Pandey et al., QUANTITATIVE APPLICATION OF DRIFT SPECTROSCOPY - DETERMINATION OF COMPOSITION OF SPECIAL ACRYLIC FIBERS, Polymer testing, 14(5), 1995, pp. 489-494
A fast, direct and nondestructive method involving no sample preparati
on has been developed for recording a well resolved and reproducible s
pectrum of special acrylic fibre, (SAF), a precursor for carbon fibre
using diffuse reflectance infrared Fourier transform (DRIFT) spectrosc
opy. A novel method has been developed for determining the composition
of SAF containing both acrylate and carboxylic acid comonomers. The s
pecial feature is that no standard samples (of known composition) are
required.
