摘要:
A tire wheel assembly having, attached to a tire/rim cavity, a run flat core member formed such that a high rigidity ring-shaped shell is supported at a rim with elastic rings, which are composed of a thermoplastic elastomer composition comprising a rubber composition (B) dispersed in a thermoplastic resin (A) or a hydrogen bondable thermoplastic elastomer comprising an elastomer polymer having a carbonitrile group-containing group and a heterocyclic amine-containing group at the side chain thereof and/or a composition of the thermoplastic elastomer, giving a tire wheel assembly of a run flat tire, in particular a tire wheel assembly capable of recycling the elastic rings for forming the core member.
摘要:
A thermo-reversible, crosslinkable elastomer, a composition containing the same, a rubber-bonded body and a rubber structure containing the rubber-bonded body are disclosed. The thermo-reversible, crosslinkable elastomer has an elastomer main-chain and a crosslinkable portion having at least one group selected from the group consisting of acid anhydride group and hydroxyl group. The thermo-reversible, crosslinkable elastomer can form stable crosslinked structure at room temperature, thereby having rubber plasticity, show sufficient melt flowability at molding temperature of general thermoplastic resin, and repeatedly reproduce crosslinking formation and crosslinking dissociation.
