“…Variation of molecular weight was observed during reaction between rubber and ozone in carbon tetrachloride as shown in Figure 2. Razmovskii et al (56) studies the degradation of cis-1,4-polybutadiene (SKD) rubber solution in octane in the presence of 1 x 10 -5 to 8 x10 -5 mol/L O 3 at -26 to +48°C, proceeds via isomerisation and dimerisation of RCHO 2 -ion intermediate and results in the formation of ozonides. The degradation of SKD rubber obeys the Arrhenius equation and the activation energy of degradation of SKD rubber in the presence of ozone is 9.6 ± 1.4 kJ/mol.…”
