Abstract
The decrosslinking reaction of XLPE in supercritical fluid was studied. Reaction temperature and solvent were dominant parameters to affect the reaction rate. Although the molecular weight of polyethylene decreased after decrosslinking reaction, no other functional groups were not formed and the mechanical strength didn’t decrease. The kinetic model based on gel concentration agreed well with experimental results. The continuous decrosslinking process was possible using a single-screw extruder.
