1. A mineral-bound elastomeric material, comprising:
an elastic polymer;
a polymer matrix unit comprising at least one connecting group and a mineral binding group; and
inclusions of a metal carbonate bound to the polymer matrix unit via the mineral binding group,
wherein the elastic polymer is covalently bound to the polymer matrix unit via the connecting group;
wherein the connecting group comprises a saturated or unsaturated organic group comprising 8 to 20 carbon atoms and at least one atom selected from a group consisting of O, N, S and a halogen, and the organic group connects the elastic polymer to the mineral binding group; and
wherein the mineral binding group is bound to the metal carbonate via a functional group selected from the group consisting of a carboxylic acid, a carboxylic acid salt, a carboxylic acid derivative, an anhydride, an anhydride derivative, a phosphate, a phosphate salt, a phosphate derivative, and a sulfonate.
