摘要：

A series of polyacrylate emulsions were blended with tackifier resin emulsions such asmodified rosin emulsion, C5 resin and C9 resin emulsion. The miscibility of the polyacry-lates and tackifier resins was investigated by means of SEM and visual observation. Thephase diagrams of the miscibility change systematically with the polarity of polyacrylatesand tackifier resins. The influence of the content of the tackifier resins on the adhesionproperties of the polyacrylate emulsions were also studied. The results show that the180℃ peel strength is improved as the amount of the tackifier resin increases and comesto a maximum at a specific content. The ball tack property decreases slightly and the holdstrength changes complicatedly as the tackifier resin increases.
