Abstract

The disclosure relates to a method for modifying the rheology of a polymer and a polymeric composition obtained by the method. The composition comprises at least one organic peroxide and water in emulsion form. The polymer may comprise a polyolefin. The method comprises extruding a molten polymer and the composition and removing volatile compounds from the molten polymer.
