Abstract
Official abstract text for this publication.
Inflatable article equipped with an elastomer layer impermeable to inflation gases, said elastomer layer comprising at least, as the predominant elastomer, a thermoplastic SIBS elastomer comprising a polyisobutylene block comprising an amount of units derived from one or more conjugated dienes ranging from 0.5% to 6% by weight relative to the weight of the polyisobutylene block, and, at least one of the ends of the polyisobutylene block, a styrenic block representing at most 16% by weight of the total weight of the block copolymer. Preferably the airtight elastomer layer also comprises, as a plasticizing agent, an extender oil for the SIBS elastomer. The inflatable article of the invention is, in particular, an inner tube or a pneumatic tire for a motor vehicle.
First claim
Opening claim text (preview).
The invention claimed is: 1. An inflatable article having a vulcanized airtight layer, wherein said airtight layer comprises at least, as the predominant elastomer, a thermoplastic SIBS elastomer in the form of a block copolymer composed: 1) of a polyisobutylene block having a number-average molecular weight ranging from 25,000 g/mol to 350,000 g/mol and a glass transition temperature of less than or equal to −20° C., and comprising an amount of units derived from one or more conj…
