。Prior Art and Problems to be Solved by the Invention Butyl rubber is being used in various fields due to its excellent physical and chemical properties such as heat resistance, resistance to oxygen deterioration, and gas impermeability. Hot melt compositions containing tackifying resins and the like are known. However, due to the relatively high molecular weight of butyl rubber, it is unavoidable that the viscosity becomes high in the molten state, resulting in poor coating workability.
The discharge amount decreased or the adhesion was poor.
