PROBLEM TO BE SOLVED: To provide an inner liner for a pneumatic tire which has gas barrier property such as oxygen, improves durability of a tire by suppressing the deterioration of framework rubber inside the tire due to oxygen permeation, causes no breakage or cracks due to distortion during bending and has excellent flexibility.SOLUTION: There is provided an inner liner for a pneumatic tire obtained by molding a resin composition containing a polyether polyamide (A) in which a diamine constitutional unit contains a constitutional unit derived from a polyether diamine compound (a-1) and a xylylene diamine (a-2) and a dicarboxylic acid constitutional unit contains a constitutional unit derived from an α,ω-straight-chain aliphatic dicarboxylic acid having 4 to 20 carbon atoms. |
