In most of the Research articles cyclohexane is used for the dissolution of LDPE, but in my case it has not been able to dissolved the LDPE pellets. As cyclohexane has very lower melting point and it starts to evaporates.

Technologically, polyethylene in hexane is obtained provided that the temperature is from 160 to 250 ° C and the corresponding pressure is 3.4-5.3 MPa with the obligatory presence of a titanium-magnesium catalyst or its replacement with CrO3 on silica gel.
It contacts the catalyst for an average of 13 minutes.
In order to remove polyethylene from the solution it is necessary to remove the solvent in the evaporator, then in the separator and then in the chamber with the vacuum granulator.
