Hydrogenated rosin ester latexes/waterborne polyacrylate blends for pressure-sensitive adhesives

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.
