METHOD FOR OBTAINING WAX FROM RECYCLED POLYETHYLENE
First Claim
Patent Images
1. A process for producing a wax from recycled polyethylene, comprising:
- providing an amount of recycled polyethylene;
heating the recycled polyethylene to a high temperature to undergo de-polymerization;
degrading the recycled polyethylene to smaller wax fragments;
concurrently distilling the recycled polyethylene during the degradation to collect and remove the smaller wax fragments.

Abstract
An economical and environmentally friendly method for producing waxes. In particular, the methods use thermolytic degradation concurrently with a distillation process to obtaining distilled waxes from recycled polyethylene. The resulting waxes have desirable properties, such as reduced molecular weight and narrow polydispersity, that makes the waxes useful in various applications.
