MAP of PE may be performed only by mixing this polymer with a MW absorber such as carbon or tire because PE is transparent to MW radiations.
Using carbon black or tire as MW absorber the main product is a wax, solid at room temperature [12,24].
Working with an active carbon as MW absorber [4]
or employing a more sophisticated apparatus [24]
the wax formation may be avoided and a low viscosity liquid has been collected. Active carbons enhances the efficiency of heat transfer from MW absorber to PE while the apparatus reported by Undri et al. [3,24,26]
improves the overall residence time and avoid to high boiling products to leave the reactor.
