| Abstract: | A complete mathematical model based on the reaction mechanism for the production of polyvinyl acetate was developed. Choosing measurable operating variables as inputs and taking species concentrations as main variables, the model is able to provide on-line estimates of the conversion of VAc, species' concentrations and the degree of polymerization of PVAc. The model are validated from the following aspects: the off-line analytical instruments, on-line viscosity meter and the technologic standards. It will be an important basis for guiding the operation. |
