Preparation and adhesion performance of transparent acrylic pressure sensitive adhesives: effects of substituent structure of acrylate monomer

Three different acrylate monomers containing a cyclohexyl moiety were designed and synthesized to prepare transparent acrylic pressure sensitive adhesives (PSAs) comprised of semi-interpenetrated structured polymer networks. The effects of substituent structure in the acrylate monomer on the adhesion performance of the acrylic PSA were investigated. The prepared UV-curable acrylic PSA syrups were characterized and the optical properties of their acrylic PSA film were also examined. The acrylic PSAs exhibited high transparency in the visible wavelength region. Adhesion performance was evaluated using the peel strength, cohesion strength, and probe tack tests. The adhesion properties of the acrylic PSAs depended on the substituent structure in the acrylate monomer.
