Abstract
Cis-1,4-polybutadiene was pyrolyzed in a temperature interval between 450°C and 530°C, where the temperature rise time (TRT) of the pyrolyzer used can be regarded as short. A technique called sequential pyrolysis was introduced, which was found to be less time consuming than the conventional method, and errors from sample handling were decreased. The amount of monomer detected was proportional to the pyrolysis temperature. The formation of monomer with time at each temperature could be described with a logarithmic function. The activation energy was determined to be 37.5 kcal/mole (157 kJ/mole) and the frequency factor 1011.1 s−1.Keywords
