چکیده انگلیسی
According to literature and our research, the styrene polymerization mechanism is identified by α-methylstyrene (AMS). This study investigated the basic exothermic behavior of styrene and its major derivatives, AMS, and trans-β-methylstyrene (TBMS), by two calorimeters, differential scanning calorimetry (DSC) and thermal activity monitor (TAM), to compare and evaluate their thermal kinetics on polymerization. DSC and TAM were employed for dynamic scanning and isothermal ageing tests to calculate thermokinetic parameters of styrene and styrene containing 10 ppm 4-tertiary-butylcatechol (TBC), AMS, and TBMS. Certain prominent differences were observed and discussed between AMS and TBMS obtained from DSC and TAM. All of the results could be provided to the relevant plants for lessening the degree of hazard. Results indicated that styrene, AMS, and TBMS have potential exothermic hazards, especially during the higher temperature.
