Abstract

Acrylate-based pressure-sensitive adhesives are produced by a process in which a liquid, polymerizable monomer composition containing at least one acrylate monomer is placed in a closed reaction vessel, deaerated and the monomer(s) are polymerized by exposure to ionizing radiation such as gamma irradiation. The process allows for the direct production of low-solvent or solventless acrylate-based adhesives suitable for application by hot-melt techniques.
