Dynamic simulation of hybrid differential algebraic systems using GPROMS: case study in emulsion polymerization

This paper is deals with dynamic simulation of a semi-batch polymerization reactor for emulsion copolymerization of styrene and butyl acrylate in the presence of n-dodecyl mercaptan as chain transfer agent (CTA). Mathematical model of the polymerization reaction involved is used to predict the glass transition temperature of produced polymer, global monomer conversion, the number and weight average molecular weights, the particle size distribution and the amount of residual monomers. This model, a set of hybrid differential algebraic equations (DAEs), is implemented into gPROMS environment for modeling, simulation, and optimization.
