Abstract
For the first time, a kinetic study on the supercritical decrosslinking reaction of silane-crosslinked polyethylene (S-XLPE) in a continuous process was conducted. The decrosslinking reaction in a continuous process was corresponding to the first-order reaction model in which the reaction rate was linearly proportional to the gel content. The residual gel content exponentially decreased with reaction time. Reaction constant was observed exponentially related to the reaction temperature. The continuous decrosslinking reaction revealed kinetic constants of 1.355 +/- 0.103, 2.715 +/- 0.177, and 4.348 +/- 0.218 min(-1) at 360, 380 and 390 degrees C, respectively and activation energy of 132.36 kJ mol(-1).
