    摘要： An inflatable article provided with an elastomer layer comprising at least, as major elastomer, a thermoplastic polystirene/polyisobutylene block copolymer, such as a stirene/isobutylene/stirene (SIBS) copolymer, and at least 100 phr of an extender oil. Preferably, this copolymer comprises between 5% and 50% stirene by weight, its number-average molecular weight is between 30,000 and 500,000 g/mol and its Tg is below −20° C. The extender oil is preferably a polybutene oil such as polyisobutylene (PIB) oil. This elastomer layer is able to fulfil not only the role of a self-sealing (puncture-resistant) layer, but also that of an impermeable layer, furthermore with a reduced hysteresis compared to a conventional layer based on butyl rubber. The inflatable article can be, in particular, an inner tube or a pneumatic tire for a motor vehicle.

    摘要： An inflatable article provided with an elastomer layer impermeable to the inflation gas, such as air, said layer comprising at least, as major elastomer, a thermoplastic polystirene/polyisobutylene block copolymer, such as an SIBS (stirene/isobutylene/stirene) copolymer, and expanded thermoplastic microspheres with a preferential content between 1 and 30 phr. Preferably, this copolymer comprises between 5% and 50% stirene by weight, its number-average molecular weight is between 30 000 and 500 000 g/mol and its Tg is below −20° C. Optionally, the gastight elastomer layer also contains, as plasticizer, an extender oil, especially a polybutene oil, with a preferential content between 5 and 100 phr. This gastight layer not only has excellent impermeability properties, but also a density and a hysteresis that are both reduced compared with layers based on butyl rubber. The inflatable article can be a pneumatic tire for a motor vehicle.
