AbstractIn the present paper the authors study the possibility of conducting vinyl chloride suspension polymerization at constant rate using a temperature program, as well as some physical and morphological characteristics of the obtained polymer. The elaboration of the temperature program necessary for conducting vinyl chloride suspension polymerization with constant rate was realized by two different means: empirical, on the basis of experimental data, and theoretical, on the basis of a mathematical model, which describes the kinetics of suspension radical vinyl chloride polymerization. In performing the polymerization with constant rate, the design of caloric exchange surfaces becomes much easier, an optimal using of the reaction space being in the same time ensured during the whole time of the process. The interpretation of experimental data permits us to affirm that by polymerization with constant rate can be obtained a poly(vinyl chloride) similar to the polymer with the same average molecular weight synthesized at a constant temperature with slightly weaker volumetric properties but some better thermal stability.
