Abstract
A method for producing a low viscosity polyethylene-based composition comprising melting a polyethylene-based composition; decreasing a viscosity of the polyethylene-based composition; and optionally, repeating the melting and the viscosity decreasing steps to form a low viscosity polyethylene-based composition; wherein the melting and viscosity decreasing steps are performed in a continuous process at temperature that is equal to or greater than 350° C., residence time of less than 2 min and the polyethylene-based composition is in the presence of at least one free radical generator.
