| Abstract: | Diethylene glycol ester of hydrogenated rosin (DGE‐HR) emulsion was prepared via phase inversion method and then blended with waterborne (wb) polyacrylate for pressure‐sensitive adhesives (PSAs). The preparation conditions of DGE‐HR emulsion were studied. DGE‐HR emulsion with an average particle size of about 220 nm was obtained. Furthermore, the thermal, adhesive, and viscoelastic properties and the morphology of DGE‐HR/polyacrylate composite were investigated. Thermal analysis indicated that glass transition temperatures (Tg) of the DGE‐HR/polyacrylate blends became higher as the DGE‐HR content increased and DGE‐HR did not have a significant influence on thermal stability of the blend films. Atomic Force Microscopy (AFM) observation revealed that the DGE‐HR particles added had a good miscibility with acrylic particles. Additionally, for these tackified acrylic PSAs, positive correlations between mechanical performance and viscoelastic response at bonding and debonding frequencies were also found. © 2015 Wiley Periodicals, Inc.
