A vulcanizable layered composition comprising at least two layers and at least one tie layer, wherein the first layer of the two layers is a fluid permeation prevention layer preferably comprising:

Construction comprising tie layer

A thermoplastic elastomer composition possessing superior air impermeability, excellent durability and flexibility. In particular, the composition includes (A) at least one halogenated isobutylene-containing elastomer; and (B) at least one nylon resin having a melting point of about 170&#xb0; C. to about 260&#xb0; C.; and (C) a low molecular weight polymeric nylon plasticizer; wherein: (1) the at least one elastomer is present as a dispersed phase of small vulcanized particles in a continuous nylon phase; and (2) the elastomer particles are formed by dynamic vulcanization. Use of a low molecular weight nylon plasticizer provides for improved mixing and rubber dispersion while retaining the high levels of impermeability achievable by the use of nylon resin and halogenated isobutylene-containing elastomer in a dynamically vulcanized composition. Such compositions are particularly useful in applications such as tire innerliners and barrier films or layers as well as hoses.

Low permeability thermoplastic elastomer composition

A thermoplastic elastomer composition having excellent durability and flexibility while possessing superior air impermeability. In particular, a process for producing a thermoplastic elastomer composition having high rubber content by multistage addition of at least one vulcanizable rubber component, in which the time required to substantially cure the at least one rubber component preferably is less the mixer residence time. Such compositions are particularly useful in applications such as tire innerliners and barrier films or layers.

Thermoplastic elastomer composition and process for producing same

A thermoplastic elastomer composition having improved mechanical properties and fatigue resistance comprising (A) a halogenated isobutylene elastomer, (B) polyamide and (C) an amine component selected from tertiary amines and secondary diamines, wherein the elastomers are dispersed as a domain in a continuous phase of the polyamide.

Thermoplastic elastomer composition having viscosity-enhanced and vulcanized elastomer dispersions
