Abstract
Polybutadiene (PB) was epoxidized to various extens withm-chloroperbenzoic acid (MCPBA) in homogeneous solution. The thermal properties of the epoxidized PBs were investigated by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). As a result of epoxidation the glass transition temperature (T g) of PB increased by approximately 0.8°C for each 1 mol% of epoxidation. The thermal decomposition of the epoxidised PBs occurred in twostep process, while that of PB exhibited apparent one-step degradation process.
