✦ Synopsis
A dynamic computer model which can predict polymer and polymer particle properties such as molecular weight averages (MN and Mw) and long chain branching frequency) and particle size distribution for the emulsion copolymerization of styrenehutadiene has been developed. Heat balances about the latex reactor and cooling jacket with proportionaVintegra1 control are included. This modelcan be used to design, optimize and control emulsion copolymerization in well-mixed stirred tank reactors operated in batch, semi-batch and continuous modes for transient and steady-state operation. Details of modelling are described and then applications of the model are shown to illustrate the range of operational conditions of various production systems that can be investigated.
