  • Use of mono-substituted succinic anhydride
    Patent number: 11708478
    Abstract: The present invention refers to the use of at least one mono-substituted succinic anhydride before or during extrusion of a polymer composition comprising polylactic acid as polymer component and at least one calcium carbonate-comprising 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 polylactic 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
