In this study, a simple method was purposed to prepare "Cool-off" function of a pressure-sensitive adhesive (PSA). The synthesis method as follows: vinyl acetate, behenyl acrylate, isobornyl acrylate and acrylic acid were polymerized in toluene containing AIBN as a radical initiator. Physical properties of the adhesive were investigated using differential scanning calorimetry (DSC), thermal gravimetric analysis (TGA), thermomechanical analysis (TMA). And peel test was investigated using universal testing machine (UTM). In peel test, the PSA tape was attached onto a stainless steel (SUS) plate at 20℃ and then peeled at given temperatures with a peeling rate of 300mm/min. |
