Nitrogen Poisoning of HDPE and LLDPE based on Chemically Recycled Post‐Consumer Plastic via a Kinetic and Microstructural Modeling Technique

Chemical recycling of plastic waste has promise as a complementary technology to increase eco-efficiency plastics life cycles. Accumulation impurities in feed streams can affect sensitive compounds such the Ziegler–Natta catalyst systems commonly used produce polyolefins high density polyethylene (HDPE) and linear low (LLDPE). In poison study, influence impurities—more specifically NO N2O—on system are investigated comprehensively terms kinetic behavior activity rates. A product composition analysis gives insights into properties molecular weight distribution (MWD), comonomer (CCD), melting point, crystallinity. By applying known modeling techniques (kinetic modeling, MWD, CCD deconvolution modeling), information beyond analytical data is obtained. The results study show that both poisons significantly kinetics reduce activity. N2O influences primarily while poisoning strongly affects LLDPE samples. Since mechanical polymers produced depend on factors MWD CCD, may their processability applicability.
