Hydrogenation of synthetic cis‐14‐polyisoprene and natural

The apparent activation energies for the hydrogenation of synthetic cis‐14‐polyisoprene and natural rubber were evaluated to be 79.8 and 75.6 kJ/mol respectively. The mechanistic aspects of these alytic processes were discussed on the basis of observed kinetic results. The addition of some acids showed an effect on the hydrogenation rate of both rubbers. The thermal properties of

The predominant version is known as cis-14 which as the repeating unit of polybutadiene has the following structure: Two other structures are the trans-14 and the 12 side vinyl isomers. Polybutadienes are made either with high cis content 95 to 97 percent or with only 35 percent cis content along with 55 percent trans and 10 percent side vinyl.
