Embodiment

[0098]

[0099] The thermoplastic elastomers (SIB, SIBS, and SIS) used in the production of the polymer laminate comprising the first layer and the second layer of the present invention are produced as follows.

[0100] [SIB]

[0101] Into a 2 L reaction vessel equipped with a stirrer, 589 mL of methylcyclohexane (dried over molecular sieves), 613 mL of n-butyl chloride (dried over molecular sieves), and 0.550 g of cumyl chloride were added. After cooling the reaction container to -70°C, 0.35 mL of α-picoline (2-picoline) and 179 mL of isobutene were added. Further, 9.4 mL of titanium tetrachloride was added to start polymerization, and the solution was reacted for 2.0 hours while stirring the solution at -70°C. Next, 59 mL of styrene was added to the reaction container, and after continuing the reaction for 60 minutes, a large amount of methanol was added to terminate the reaction. After removing the solvent and the like from the reaction solution, the polymer was dissolv...

Abstract

A pneumatic tire provided with an inner liner on the inner tire side of a carcass ply which extends between a pair of beads, said inner liner comprising a first layer located on the inner tire side and a second layer located in such a manner as to be in contact with a rubber layer of said carcass ply, said first layer being formed of a thermoplastic elastomer composition which comprises, as the main component, a styrene-isobutylene-styrene block copolymer, and said second layer being formed of a styrene-based thermoplastic elastomer composition, wherein: (a) the thermoplastic elastomer composition(s) of said first layer and / or said second layer contain 0.1-100 parts by mass of a tackifier per 100 parts by mass of the thermoplastic elastomer; or (b) said second layer contains 10-80 mass%, relative to the thermoplastic elastomer component, of a styrene-isobutylene-styrene block copolymer.

Description

technical field [0001] The present invention relates to a pneumatic tire having an inner liner, and more particularly to a pneumatic tire having reduced rolling resistance while reducing the growth of cracks in the inner liner accompanying repeated flexing deformation during tire running, reducing the drop in tire internal pressure. Background technique [0002] In recent years, due to the strong social demand for low fuel consumption of automobiles, people are seeking to reduce the weight of tires. Even in tire components, there are tires that are installed inside the tire and have the function of reducing the leakage of air from the inside of the pneumatic tire to the outside. In the inner lining layer, weight reduction, etc. are also being carried out. [0003] Conventionally, the rubber composition for an inner liner improves the air permeation resistance of the tire by using, for example, a rubber formulation mainly composed of butyl rubber containing 70 to 100% by mass...
