uses of at least one monosubstituted succinic anhydride and a polymeric composition, method for reducing polymeric decomposition during processing and / or decreasing the flow rate and / or increasing the viscosity of a polymeric composition, and, article.

摘要

The present invention relates to the use of at least one monosubstituted succinic anhydride before or during the coextrusion of a polymer composition comprising at least one polymer as a polymeric component and at least one material comprising calcium carbonate as a filler to reduce polymer decomposition during use. processing and / or to decrease the flow rate of such coextruded polymer composition by at least 10% and / or to increase the viscosity of such coextruded polymer composition by at least 10% compared to the same polymer composition as 10 was treated with the same. likewise in the absence of any monosubstituted succinic anhydride, wherein the polymeric composition does not comprise polylactic acid.
