Abstract
PURPOSE: To provide a rubber compsn. for an inner liner of a pneumatic tire for automobiles, which has such characteristics that air transmission rate is reduced, adhesion between different kinds of adjacent rubbers is increased and thermosetting is inhibited, by blending a resin homogenizing agent with a raw rubber consisting of a halogenated butyl rubber and a diene rubber.
CONSTITUTION: 5W50pts.wt. resin homogenizing agent (such as "Struktol 40MS " obtd. by blending not less than 85wt% petroleum resin with not more than 15wt% acetyl compd.) in addition to conventional additives is added to 100pts.wt. raw rubber consisting of 50W100pts.wt. halogenated butyl rubber and 0W50pts.wt. diene rubber such as NR, IR, BR or SBR to obtain the desired rubber compsn. This compsn. is used for particularly large-sized tires for construction vehicles, which are constructed of biasply.
