摘要：

The effectiveness of a low-pressure hydrogenation process for the selective hydrogenation of the vinyl-1,2, cis-1,4, and trans-1,4, structural units in high molecular weight polybutadienes has been explored using H-1 NMR, FT-IR, and Raman spectroscopy. The spectroscopic results indicate that it is possible to monitor the hydrogenation process by analysis of partially hydrogenated polybutadienes. The NMR measurements have made it possible to see the incorporation of an aromatic impurity in the polymer which results from a side reaction during hydrogenation. The first report is made of the use of Raman spectroscopy for analyzing the hydrogenation of a polydiene, and it is shown that FT-IR represents an improvement on earlier dispersive measurements of these processes.
