AN IR SPECTROSCOPIC STUDY OF THE STRUCTUR E OF POLYCAPROAMIDE FIBERS WITH GRAFTED POLY(GLYCIDYL METHACRYLATE)

IR spectra of polycaproamide fiber, poly(glycidyl methacrylate), and p olycaproamide fiber with grafted poly(glycidyl methacrylate) were regi stered and analyzed. The corresponding deconvolution spectra were comp uted. A model spectrum of the graft copolymer was simulated. The spect ral regions that are sensitive to localization of the chains of grafte d poly(glycidyl methacrylate) were identified: 3500 - 3100 cm-1 (stret ching vibrations of NH groups); 1700 - 1500 cm-1 (Amide I and Amide II absorption bands); 1030 - 900 CM-1 (Amide IV); 720 - 640 cm-1 (Amide V). It was found that poly(glycidyl methacrylate) is grafted to the ma cromolecules of polycaproamide via an amide nitrogen.
