Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain the subject composition improved in physical characteristics such as strength and hardness without lowering processability in kneading operations, etc., by including a rubber other than butyl rubber, an epoxy resin and a vulcanizing agent. SOLUTION: This composition is obtained by including (A) a rubber other than butyl rubber (e.g. a styrene-butadiene rubber), (B) an epoxy resin (e.g. a novolak type epoxy resin) and (C) a vulcanizing agent (e.g. sulfur). The epoxy equivalent of the component. B is preferably
