The progress in the research of kinetics modeling for the semi - continuous emulsion polymerizaiton was introduced

and the method of the modeling was discussed also. It was summed up that there exist three types of model

the fundamental model

real model

and general model. Model equations

which were set up by means of some assumptions

and according to mass balance

energy balance and polymerization rate equation

were solved by the numerical method combined with evaluation of model parameters

use of known model parameters and calculating methods of model variables.
