Notes:
The polybutadiene (PB) content and its microstructure in different grades of high impact polystyrene (HIPS) has been studied by various spectroscopic techniques. PB is characterized by deformation bands in FTIR spectroscopy at 994, 967, 912, and 729 cm-1. FT-Raman was used for higher constant resolution over the range of wave numbers. It provides reasonable signal to noise ratios in near IR excited Raman. Proton and 13C-NMR spectroscopy was utilized for the determination of polybutadiene content in HIPS and tacticity, and reactivity ratios. © 1996 John Wiley & Sons, Inc.
