Abstract
Polylactide resins are branched by reaction with a mixture of a polyene compound and a cyclic peroxide. 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 sheet and film extrusion, extrusion foaming, extrusion coating and fiber processing. They are characterized by easy processing and allow for broadened processing windows.
