Continuous Decrosslinking of Silane Crosslinked Polyethylene:Rheological and Thermal Properties of Decrosslinked PE

In this research we developed a continuous process for recycling of crosslinked polyethylene using conventional extruders. The recycling mechanism was thermal-mechanical-chemical, and methanol was used as a recycling agent. The crosslinked polyethylene was prepared via silane grafting- water crosslinking method. Rheological properties were monitored as an indication of the amount of decrosslinking. It was found that by selecting proper processing condition the rheological behavior of decrosslinked PE will be similar to that of virgin polymer
