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.
