PURPOSE:To provide a rubber composition which can give a pressure-sensitive adhesive tape base excellent in adhesion to a pressure-sensitive adhesive by using a copolymer obtained by mixing ethyl acrylate with a specified amount of glycidyl acrylate and a specified amount of n-butyl acrylate and compolymerizing the mixture. CONSTITUTION:100 pts.wt. ethyl acrylate is mixed with 0.2-30 pts.wt. glycidyl acrylate and 10-500 pts.wt. n-butyl acrylate. The mixture is copolymerized into a copolymer. This copolymer as a base is optionally mixed with an acrylonitrile homopolymer having the effect of improving oil resistance to produce a rubber composition. This composition can be desirably used for especially a base of a pressure-sensitive adhesive tape to be used for mounting a side protection molding to the body of an automobile, and does not cause interfacial peeling between the base and the pressure-sensitive adhesive applied thereto. |
