Key statement: The present invention is directed to a pneumatic tire comprising a carcass and an innerliner in direct contact with the carcass, the innerliner comprising: a film comprising a blend of a polyamide, an [alpha]-olefin graft copolymer, and an ionomer; and an adhesive layer disposed between the film and the carcass, the adhesive layer comprising: a polymeric amine and a resorcinol-formaldehyde-latex (RFL) adhesive.

It is reported that due to using BPO, possible reactions as following can be occurred: (a) the chain-transfer reaction between the growing chains and the backbone, which forms active sites on the backbone; (b) the monomers add to active center on the backbone to give a graft copolymer; (c) the graft copolymer chain growing on the backbone in which termination of the process is likely to occur in one of the chain-transfer or combination reactions involving the growing chain radical on the backbone.
