摘要： A process for producing a thermoplastic resin composition in which the continuous phase comprises an ethylene/vinyl alcohol copolymer (A) and a polyamide resin (B) and the dispersed phase comprises an acid-modified polyolefin elastomer (C), the process being characterized by comprising: step (I) in which an ethylene/vinyl alcohol copolymer (A) and an acid-modified polyolefin elastomer (C) are kneaded to form a mixture in which the acid-modified polyolefin elastomer (C) has been dispersed in the ethylene/vinyl alcohol copolymer (A); step (II) in which a polyamide resin (B) is subsequently added to the mixture obtained in step (I), and the resultant mixture is further kneaded; and step (III) in which a terminal-blocking agent (D) for the polyamide resin (B) is subsequently added to the mixture obtained in step (II) in an amount of 0.1-5 parts by mass per 100 parts by mass of the polyamide resin (B), and the resultant mixture is melt-kneaded at a temperature not lower than the melting point of the polyamide resin (B).

摘要： Provided is a tire inner liner with which it is possible to suppress resistance to flex fatigue during tire travel and peeling failures at high temperatures, and also reduce rolling resistance at low temperatures. A tire inner liner comprising a material that contains a thermoplastic elastomer composition, which is constituted from a thermoplastic resin or thermoplastic-resin component and an elastomer component, said tire inner liner characterized in that, in a temperature dependent curve of tanδ of the material, the maximum value of tanδ occurs between 20°C and 70°C inclusive.

摘要： Provided is a pneumatic tire which has low air permeability and undergoes a small change in air permeability due to fatigue. A pneumatic tire of the present invention contains a layer which is formed of a thermoplastic elastomer composition that is composed of (A) a modified ethylene-vinyl alcohol copolymer to which an aliphatic polyester is grafted, (B) a polyamide resin and (C) a modified rubber having an acid anhydride group or an epoxy group.
