The subject invention is directed towards tire components which are comprised of rubber compositions which are comprised of (1) about 2 phr to about 45 phr of a trans-1,4-isoprene-butadiene copolymer which has about 4 weight percent to about 16 weight percent butadiene repeat units and from about 84 weight percent to about 96 weight percent isoprene repeat units, wherein the trans-1,4-isoprene-butadiene copolymer has a Mooney ML 1+4 viscosity which is within the range of about 35 to about 80; and (2) about 55 phr to about 98 phr of at least one other elastomer, preferably a diene based elastomer. The most preferred tire components are those which contain cord reinforcements and require adequate green strength to enhance the tire building and shaping process to maintain cord integrity in the final cured tire.

The present invention is concerned with the field of polymer chemistry and relates to rubber or elastomer compositions as can be used for vehicle tires, and to a method for the production of the rubber or elastomer compositions.

The object of the invention is that in particular the elastic modulus of the compositions can be adapted depending on the temperature and/or the application conditions, and is a cost-effective and easily implemented method for the production of the compositions.

The object is attained by rubber or elastomer compositions that contain at least one rubber or elastomer matrix and at least 20 to 150 phr of a phase change material in solid or liquid form. In the methods according to the invention, at least one rubber and at least 20 to 150 phr of a phase change material in solid or liquid form are used, the composition is mixed or the at least one rubber is at least brought into contact with the phase change material, and further processing steps can be performed and a vulcanization can be performed.
