Abstract: A tire sensor attachment structure is provided. The tire includes a pair of bead areas, a sidewall extending from each respective bead area to a tread, a carcass extending toroidally between each of the bead areas, and an innerliner that is disposed radially inwardly of the carcass. A sensor housing is attached to the innerliner, and defines an interior chamber. A sensor is disposed in the chamber. The tire sensor attachment structure includes a compressible body that is disposed in the chamber between the sensor and the innerliner.

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.

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.
