Low temperature electron beam polymerization
 A method for polymerizing a free-radical initiated adhesive syrup of an C.sub.8-13 alkyl acrylate monomer, optionally including one or more comonomers, by irradiating the adhesive syrup with about 20 to 100 kGy of accelerated electrons over a residence time of greater than 1 second at a temperature below 20.degree. C. The method produces a pressure-sensitive adhesive with balanced peel adhesion, shear strength and conversion.
