Resumen:
This work presents (in a wider perspective), some of our recent developments in the
mathematical modeling and control of bulk polymerization for the production of HIPS. The
recent model by Casý´s assumes the polymerization to be heterogeneous, and it calculates (in
two phases) the global molecular structure of
the three polymeric components of HIPS (free
polystyrene, unreacted polybutadiene, and
graft copolymer). At present, a model is being
developed capable of estimating the average
particle morphology (salami or core-shell).
Assuming a continuous bulk HIPS process
as homogeneous, Luciani estimated the evolution
of the MFI of the final product during
changes of grade, with the aim of minimizing
the intermediate off-spec product. Finally, an
unpublished simulation is presented that
describes the transitions between the steady
state of a HIPS-grade and that of a general purpose
polystyrene.
