  • Patent number: 11505678
    Abstract: The use of at least one mono-substituted succinic anhydride is described before or during compounding of a polymer composition including at least one polymer as polymer component and at least one calcium carbonate-based material as filler. The use of the at least one mono-substituted succinic anhydride can reduce the polymer decomposition during processing and/or can decrease the melt flow rate of such a compounded polymer composition by at least 10%. The use can also increase the viscosity of such a compounded polymer composition by at least 10%, in comparison to the same polymer composition that has been treated the same way in the absence of any mono-substituted succinic anhydride, wherein the polymer composition does not include polylactic acid.
