AB  - The crosslinking behavior of polyethylene (PE) determines its exceptional 
      performance and application. In this study, we investigated the crosslinking 
      behaviors of different PE resins through model simulation and rheological 
      methods. Specifically, the mathematical equation of "S" model was established for 
      PE resin. According to this equation, the optimal maximum gel content for 
      high-density polyethylene (HDPE) was found to be around 85%. Moreover, the 
      maximum crosslinking degrees for different PE resins depended largely on their 
      density and molecular weight. The melt viscosities before crosslinking in PE 
      resins were highly influenced by their melt index. The higher melt indexes 
      resulted in the lower storage moduli, improving melt processability during 
      processing. In addition, the crosslinking rates of PE resins were strongly 
      influenced by peroxide concentration, independent of PE resin structures. For 
      high molecular weight and low-density PE resins, they exhibited decreased ti 
      values, increased A(0) values, and decreased k6 values. However, there were no 
      noticeable variations in the values of k2 and phi among different PE resins. All 
      simulated modeling outcomes showed remarkable consistency with the experimental 
      rheological data. These findings are of strong significance in the industrial 
      manufacture of PE resin.
