In studies using DEPDC as an initiator, mixing rate did not have a pronounced effect upon either amount of PVDF produced, polydispersity, or average molecular weight [13, 23].
Increasing molecular weight, as well as increasing polydispersity was also observed with increasing residence times using a continuously stirred tank reactor (CSTR) with DEPDC initiated polymerization with a VF2 concentration of 2.8 mol/L, molecular weight and polydispersity was not observed to increase with a monomer concentration of 0.78 mol/L [23].
In other works using 0.03 mol/L of DEPDC as an initiator in a CSTR with a residence time of 21 min and a reaction temperature of 75[degrees]C, the PDI was observed to increase from 1.5 to 5.5 over VF2 concentrations from 0.75 to 3.5 mol/L [26], This experimental study using TBPA as an initiator uses less initiator at a higher temperature compared to DEPDC.
