PROBLEM TO BE SOLVED: To provide a rubber composition for a tire inner liner produced by using a reclaimed rubber. SOLUTION: The rubber composition for tire inner liner is produced by compounding 100 pts.wt. of a stock rubber containing≥70 pts.wt. of butyl rubber or halogenated butyl rubber with 2-20 pts.wt. of a reclaimed rubber having Mooney viscosity of 10-30 and a weight-average molecular weight (Mw) of the rubber component of 20,000-70,000. Preferably, not less than 80 wt.% of the rubber component of the reclaimed rubber is butyl rubber or halogenated butyl rubber. COPYRIGHT: (C)2007,JPO&INPIT
