This branching method produces a product that has a very high polydispersity, a high branching number (B.) and excellent melt strength, without forming large amounts of gelled material. The branched polylactide resins are useful in many melt processing operations, in particular 0 sheet and film extrusion, extrusion foaming, extrusion coating and fiber processing. They are characterized by easy processing and " allow for broadened processing windows.
