(618bf) On Multiplicity In Conversion of Monomers In Transient CSTR

Transient analysis of continuous polymerization by free radical methods in a CSTR was completed. The system was characterized by Damkohler number for initiator, Da_D and Damkohler number for monomer, Da_M .The initiator concentration can be described using a simple ordinary differential equation. The governing equation to describe the monomer concentration was non-linear. This equation was solved for by 4^th order Runge Kutta method using MS Excel in a desktop computer. Multiplicity was found  at transient coversion of monomer X =0.84.  There are two dimensionless times associated with this conversion. These can be seen from Figure 2.0 to be t = 1.26 and t = 2.6.  The maximum transient conversion of momomer X for the parameters used in the simulation study was found to be 0.863.
