In this study, the properties of acryl emulsion with adjunction procedures of tackifier resin and tackifier emulsion were investigated. Glass transition temperature of acryl emulsions was increased with the content of tackifiers. The initial strength showed the maximum value when the contents of tackifier resin and tackifier emulsion were 10 phr and 15 phr, respectively. Additionally, the strengths on heat and water resistances were increased with the contents of tackifier.

In this study, water-based acrylic tackifier with different contents of 1-dodecanethiol(n-DM), a chain transfer agent(CTA), were synthesized to improve the performance and adhesive properties of water-based acrylic pressure sensitive adhesive(PSA). In order to investigate the change in physical properties according to the amount of water-based acrylic tackifier added, 10/20/30 phr of water-based acrylic tackifier was added to the water-borne acrylic emulsion to measure the physical properties. The molecular weight and glass transition temperature(T_g) of the synthesized water-based acrylic tackifier tended to decrease as the content of n-DM increased. When a water-based acrylic tackifier was added to the water-borne acrylic emulsion, the peel strength and heat-resistance were increased. Also, when the water-based acrylic tackifiers were added at 10 phr or 20 phr, the best value was shown.
