摘要： Provided is a crosslinked elastomer that can easily be decrosslinked. The crosslinked elastomer is obtained through crosslinking of a diene elastomer that has a vinyl bond content of 30 mass% or less and a weight-average molecular weight of 1,000 or more. The crosslinked elastomer includes a diboronic acid ester skeleton unit represented by a specific general formula (1) at a crosslinking site.

摘要： Provided is a method of crosslinking an elastomer that uses an elastomer that can easily be crosslinked and decrosslinked. The method of crosslinking an elastomer includes a step of causing contact of an elastomer including a monoboronic acid ester-containing functional group represented by a specific general formula (4) with a diboronic acid compound in the presence of a solvent. The solvent has an SP value of not less than 10 (cal/cm3)1/2 and not more than 13 (cal/cm3)1/2 and includes at least a single solvent having an SP value of not less than 8 (cal/cm3)1/2 and not more than 10 (cal/cm3)1/2.

摘要： A tire includes a rubber member and a round tire frame made of a resin material. The resin material includes a thermoplastic elastomer, and has a deflection temperature under load of 150 °C or higher. The thermoplastic elastomer includes a soft segment and a hard segment derived from a polyamide. A minimum number X of carbon atoms present between nitrogen atoms in the main chain of the polyamide in the hard segment and a molecular weight Y of the hard segment satisfy the following Formulae 1 to 3: Y = 250X + A 6 ≤ X ≤ 12 − 1000 ≤ A ≤ 1500.

摘要： Provided is a method by which a crosslinking site of a crosslinked elastomer can easily be returned to a non-crosslinked state. The method of returning a crosslinking site of a crosslinked elastomer to a non-crosslinked state includes a step of causing contact of a crosslinked elastomer including a diboronic acid ester skeleton unit represented by a specific general formula (1) at a crosslinking site with a monoboronic acid compound represented by a specific general formula (3) in the presence of an organic solvent having an SP value (solubility parameter) of not less than 7 (cal/cm3)1/2 and not more than 10 (cal/cm3)1/2. In this step, a molar abundance ratio of the monoboronic acid compound relative to the diboronic acid ester skeleton unit (monoboronic acid compound/diboronic acid ester skeleton unit) is set as more than 2 and not more than 5.
