A study on the early degradation of the non-additive polypropylene–polyethylene composite sampled between the polymerization reactor and the deactivation-degassing tank

The industrial production of polypropylene–polyethylene composites (C-PP-PE) involves the generation of waste that is not usable, resulting in a significant environmental impact globally. In this research, we identified different concentrations of aluminum (8–410 ppm), chlorine (13–205 ppm), and iro...
