Resumen:
Polymer recycling is an attractive solution in order to reduce plastic waste accumulation. In this way, mixtures of discarded Polystyrene (PS) and Polyethylene (PE) may be compatibilized through a Friedel-Crafts alkylation. The reaction, catalyzed byAluminum Chloride (AlCl3) and styrene, produces a graft copolymer that improves the properties of the blend.As an initial stage in the development of a comprehensive model of the compatibilization process, we modeled the effect of AlCl3 on PS, since PS is degraded in compatibilization conditions.Final polymer properties depend strongly on molecular weight and molecular weight distribution (MWD). Then, controlling these parameters would allow obtaining materials with certain desiredproperties. In this work, probability generating functions areused in order to predict the MWD during PS degradation for various catalyst concentrations.
