Abstract: A curable elastomer composition includes a crosslinkable polymer, and a filler selected from surface-reacted calcium carbonate, precipitated hydromagnesite, or a mixture thereof, wherein the surface-reacted calcium carbonate is a reaction product of natural ground calcium carbonate or precipitated calcium carbonate with carbon dioxide and one or more H3O+ ion donors, wherein the carbon dioxide is formed in situ by the H3O+ ion donors treatment and/or is supplied from an external source. Furthermore, the disclosure relates to a cured elastomer product formed from said composition, an article including the cured elastomer product, a method of producing a cured elastomer product, and use of the filler for reinforcing a cured elastomer product.

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 anhyride 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.
