The present invention refers to the use of at least one mono-substituted succinic anhydride before or during compounding of a polymer composition comprising at least one polymer 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 a compounded polymer composition by at least 10 % and/or to 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 comprise polylactic acid.
本发明是指在由至少一种聚合物(作为聚合物组分)和至少一种含碳酸钙的材料 (作为填料)组成的聚合物组合物复合之前或复合过程中,使用至少一种单取代琥珀 酸酐、减少加工过程中的聚合物分解,和/或使这种复配聚合物组合物的熔体流动速率降低至少 10%,和/或使这种复配聚合物组合物的粘度增加至少 10%。
