Abstract : The dependence of the average molecular weight of polyvinylchloride on the technological process parameters has been established on the basis of an experimental investigation of the process of the emulsion polymerization vinylchloride. Changes of the reactor load over wide limits occur in the process of the reactor run due to the consumption of vinylchloride; changes also occur in the consumption of the initiator. In order to maintain the stability of the mean polyvinylchloride molecular weight, it is necessary to change the reaction temperature in such a way that with the variations of other technological parameters the quality of the product remains unchanged. Discussed is a pneumatic computer intended for computing the relationship describing the optimum temperature conditions of the process of emulsion polymerization of vinylchloride, depending on the values of the given magnitude of the H. Fikentscher constant and current values of the initiator concentration, and vinylchloride and emulsion water expenditures. (Author)
