  • Patent number: 11912798
    Abstract: Novel functionalized rubbers having low hysteresis and good compatibility with fillers, such as carbon black and silica, have been synthesized. These functionalized rubbers, including functionalized polybutadiene rubber and functionalized styrene-butadiene rubber, can be beneficially used in making a wide variety of rubber products that have enhanced physical properties. These improved properties are realized because the functional groups therein improve compatibility with reinforcing fillers that are typically included in such rubber compounds. These functionalized rubbers are comprised of polymer chains of the structural formula: wherein Polydiene represents a polymer chain which is comprised of at least one diene monomer and wherein R1 and R2 can be the same or different and represent alkyl groups containing form 1 to 8 carbon atoms. These rubbers can also be functionally terminated with a silicon containing terminator.

  • Patent number: 11890896
    Abstract: A preparation method of itaconate-butadiene bio-based engineering rubber belongs to the bio-based engineering rubber area. The bio-based engineering rubber of the present disclosure is formed through chemical crosslinking of copolymers, which are formed by polymerization of itaconate and butadiene emulsion. The number average molecular weight of the itaconate-butadiene copolymer is about 53000-1640000, and weight-average molecular weight is about 110000-2892000. Itaconate-butadiene copolymers are formed by polymerization of itaconate and butadiene emulsion, then and chemical crosslinking of the copolymer is performed to form bio-based engineering rubber using a traditional sulfur vulcanizing system. The bio-based engineering rubber has high molecular weights as well as lower glass-transition temperatures and can be vulcanized using the traditional sulfur vulcanizing system.

    Abstract: Aspects of the present invention relate to methods for characterizing a multi-layered tire tread. In one example, a method comprises providing a first rubber composition having a first refractive index and providing a second rubber composition having a second refractive index. The method further comprises determining a difference between the first refractive index and the second refractive index and comparing the difference to a threshold refractive index. In addition, the method comprises adding a refractive index modifier to the first rubber composition and/or second rubber composition in case the comparison provides that the difference is lower than the threshold refractive index, so that the difference is greater than, or equal to, the threshold refractive index.

  • Patent number: 11865875
    Abstract: A tire high temperature forecasting system includes at least one tire that supports a vehicle, and at least one sensor mounted on the tire for measuring a temperature of the tire. An electronic memory capacity is in a unit mounted on the tire for storing tire identification information. A processor is in electronic communication with the sensor and the electronic memory capacity, in which the processor receives and correlates the measured temperature, a time of the temperature measurement, and the tire identification information. Transmission means transmit the measured temperature, a time of the temperature measurement, and the tire identification information to a remote processor. The remote processor executes a forecasting model, and the forecasting model generates a forecast estimate. If the forecast estimate includes a predicted high temperature that is greater than a predetermined high temperature threshold for the tire, an alert is generated by the forecasting model.
