    摘要: 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.

    摘要: The present invention refers to a surface treated filler material product comprising a) at least one calcium carbonate-containing filler material and b) a treatment layer on the surface of the at least one calcium carbonate-containing filler material comprising i. maleic anhydride grafted polyethylene and/or maleic anhydride grafted polypropylene and ii. at least one hydrophobizing agent. Furthermore, a process for preparing the inventive surface treated filler material product is disclosed, as well as a polymer composition comprising at least one polymeric resin and the inventive surface treated filler material product. Additionally, a fiber and/or filament and/or film and/or thread and/or sheet and/or pipe and/or profile and/or mold and/or, injection molded compound and/or blow molded compound comprising the inventive surface treated filler material product is disclosed as well as the use of the inventive surface treated mineral filler product in a polymer composition, for improving the mechanical and/or rheological properties of the polymer composition.

    摘要: The present invention relates to a method for transesterification of carboxylic acid esters by heterogeneous catalysis using a catalyst that is obtainable by calcination of surface-reacted calcium carbonate. The invention further relates to the use of said method in the production of fuel or fuel components, such as biodiesel. Further aspects of the present invention relate to the transesterified ester obtainable by the inventive method and to its use as fuel or as fuel component. Still another aspect of the present invention relates to a corresponding transesterification catalyst and to its use in transesterification reactions.

    摘要: 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.
