“…Based on the assumption that the heat evolved during the reaction is directly proportional to the extent of cure, the cumulative heat generated during the dynamic DSC measurement can be related to the extent of cure by where C' is the extent of cure at time t or temperature T , dH/dt is the rate of heat evolution per unit mass of resin, and AHp.o is the total heat of reaction for 100% monomer conversion. Complete conversion can be achieved by taking a sufficient amount of initiator and running the experiment at very low scan speeds (p + 0) (17)(18)(19). Indeed from Fig.…”

Nonisothermal differential scanning calorimetry (DSC) measurements were used to estimate the kinetic parameters for the curing reaction of a commercial unsaturated polyester resin. The reaction rate expression was derived from a mechanistic kinetic model based on the concept of free radical polymerization, accounting also for the diffusion controlled reaction. The total heat of reaction was evaluated in experiments run at very low scan speeds and using high amount of initiator. The kinetic parameters were found to show no dependency on the heating rate nor on the initiator concentration. Dynamic DSC measurements provide reliable kinetic data over a broad range of temperatures that is mostly significant for process simulations.

The polymerization of 2‐vinylpyridine (2VP) in dimethylformamide (DMF) with azobisisobutyronitrile (AIBN) as initiator was studied with a differential scanning calorimeter. By taking an appropriate amount of AIBN and after correction for its decomposition, the following values could be obtained: Heat of polymerization ΔHp,o = −68 ± 4 kJ/mol; overall Arrhenius activation parameters Ea = 90.0 ± 4 kJ/mol and ln A = 24 ± 1.0 (A = 2.6 × 1010 dm3/2/mol1/2. s).
