Removable pressure-sensitive adhesives (PSAs) are used in the production of self-adhesive materials such as protective films, masking tapes or biomedical electrodes. This work presents a new and environmentally friendly method obtaining this type adhesive materials, i.e., photochemically induced free radical telomerization. Adhesive binders to removable PSAs, photoreactive acrylic telomer syrup...
