Zusammenfassung:	USE OF MONO-SUBSTITUTED SUCCINIC ANHYDRIDE Abstract Fig. 1: Ymch flow rat; of CEI and examples with 20 pph fillerloading The present invention refers to the use of at least one mono -substituted succinic anhydride before or during extrusion of a polymer composition comprising poly lactic acid as polymer component and at least one calcium carbonate -comiprising material as filler, to reduce the polymer decomposition during processing and/or to decrease the melt flow rate of such an extruded polymer as well as a method for reducing the polymer decomposition during processing and decreasing the melt flow rate of a polymer composition comprising poly lactic acid as polymer component and at least one calcium carbonate -comprising material as filler, the use of a polymer composition obtainable by a process comprising the steps of a) providing at least one polylactic acid as polymer component, b) providing at least one calcium carbonate comprising material as filler, c) providing at least one mono -substituted succinic anhydride and d) contacting the components of a), b) and c) in any order and e) extruding the contacted components of step d) as well as an article comprising a polymer composition obtainable by the aforementioned process.
