A temperature indicator for a rubber article comprises a thermochromic material, wherein the thermochromic material is a component of a rubber article selected from the group consisting of tires, belts and hoses. A rubber article containing a temperature indicator is also disclosed, wherein the temperature indicator comprises a thermochromic material compounded with an elastomeric compound to form an elastomeric temperature indicator. A method of determining the operating temperature of a rubber article comprises incorporating at least one thermochromic material into a rubber article, the at least one thermochromic material having the property of changing color at a predetermined temperature, and examining the thermochromic material for a change in color, wherein the rubber article is selected from the group consisting of tires, belts and hoses.

Temperature indicator using thermochromic materials

A method for the dynamic vulcanization of polymer blends made by solution polymerization in series reactors. The polymer blends are mixed under conditions of heat and shear, and a curing agent is added to at least partially cross-link one of the blend components.
