Journal Title: Open Access Journal of Waste Management & Xenobiotics

In order to evaluate the adhesion performance, tack, peel strength, shear strength, and water solubility of pressuresensitive adhesive (PSA), we prepared PSA copolymers using 2-ethyl hexyl acrylate (2-EHA), butyl acrylate (BA) and acrylic acid (AA) with varying AA contents through solution polymerization in methanol. After preparing the PSAs, we neutralized the AA in the PSAs with potassium hydroxide (KOH). Polypropylene glycol (PPG) was blended with the PSAs as a surfactant before testing adhesion performance and water solubility. Tack was characterized by probe tack testing, shear strength was evaluated with these hear adhesion failure temperature (SAFT) method, and peel strength was measured by 180° peel testing. The water solubility test was performed by comparing weight of before immersing the PSA blends in distilled water and after removing the PSAs blends from water. Water solubility was increased along within creased AA and PPG contents in the PSA blends.
