On the basis of electrical analogy method reported in the paper (1), the polycondensation model of two component system was studied. The polymeric product consisted of two components polycondensation were converted into the changes of condenser charge in a row. From the following function of simulation model, it was possible to deduce the kinetics and the mechanism of polycondensation reaction.<BR>N=ΣE<BR>P= (EA<SUB>0</SUB>+EB<SUB>0</SUB>) /2EA0<BR>xn= (EA<SUB>0</SUB>+EB<SUB>0</SUB>) /ΣE<BR>where N : total number of molecules of all sizes, F : extent of reaction, χn : number average molecular weight, ΣE : total voltage of condenser of circuit, EA<SUB>0</SUB> : voltage of CA condenser of circuit at the start, EB<SUB>0</SUB> : voltage of CB condenser of circuit at the start.<BR>In deriving the electric circuit model, the by-products model and the cyclization-products model were discussed as the expression for the network structure of circuit. The cyclization-products model was made up of diodes, resistances and condensers. The by-products model was made up of condensers.
