The specifics of this chemical reaction is the significant viscosity increase by few orders of magnitude depending on the monomer conversion degree. The viscosity increase might cause a problem in a batch reactor since the higher input power is necessary to maintain the proper mixing intensity. The sufficient reaction heat removal is also important because the reaction is highly exothermic. Nevertheless, the elevated temperature is beneficial for the reaction rate as well as for the viscosity decrease of reaction mixture, so the selection of optimal reaction conditions should take into the account both of these aspects. This contribution therefore deals with determination of viscosity of reaction mixture during polymerization reaction at different monomer conversion degrees. Rheopexy behavior is estimated on basis of polymerization kinetic measurements in the batch reactor.
