A rubber or elastomeric composition that relates to the field of polymer chemistry and that can be used for vehicle tires, and a method of making the composition, wherein the elastic modulus of the composition is determined by temperature and / or Alternatively, it is possible to provide a method that can be adapted according to use conditions and can be easily performed at low cost. A rubber or elastomer composition comprising at least one rubber matrix or elastomer matrix and at least 20 to 150 phr, preferably 30 to 80 phr, of a phase change material in liquid or solid form, wherein the phase change material is 1 μm or less. A composition having a particle size of preferably 0.01 to 0.5 μm. At least one rubber and at least 20-150 phr of a phase change material are used in solid or liquid form, the composition is mixed, or at least one rubber is at least contacted with the phase change material and further processing A method in which the process can be performed and vulcanization is performed.
