Document Type and Number:
Japanese Patent JP6804460
Kind Code:
B2
Abstract:
A pneumatic object is provided with an elastomer layer which is gastight to inflation gases, said elastomer layer comprising, as predominant elastomer, a thermoplastic elastomer in the form of a block copolymer which comprises: (a) an elastomeric block comprising at least units derived from isobutylene, and having a glass transition temperature of less than or equal to −20° C., and (b) one or more thermoplastic blocks, the thermoplastic block(s) each comprising at least one first block consisting of units derived from at least one polymerizable monomer and at least one second block, said second block(s) being a random copolymer consisting of units derived from α-methylstyrene and of units derived from β-pinene. A process for rendering a pneumatic object gastight to inflation gases is also disclosed.
