摘要
The kinetics of the polycondensation of Na2S . 3H2O and 1,4-dichlorobenzene to poly(phenylene sulfide) in 1-methyl-2-pyrrolidone as solvent was studied in a differential scanning calorimeter at temperatures from 220-degrees-C to 260-degrees-C. Stainless steel high-pressure capsules of 30 mul volume were used as micro reactors. The reaction is highly exothermic. At 220-degrees-C the enthalpy of reaction reaches a value of 180 kJ/mol. The polycondensation is characterized by an autocatalytic behaviour. The kinetics can be modelled by a second order equation with respect to the stoichiometrically charged monomers and a propagation rate constant being dependent on conversion. The activation energy of the polycondensation is 95 kJ/mol.
