Accessing to high quality of pressure-sensitive adhesives (PSAs) were achieved through photoiniferter-mediated reversible addition-fragmentation chain transfer (RAFT) polymerization. By using most general PSA components (butyl acrylate and acrylic acid), Well-controlled acrylic polymers reach up to ~1 mDa of molecular weight. Polymerization of well-controlled acrylic PSAs were characterized by spectroscopic analysis (i.e., 1H NMR and SEC) and their adhesion performance was evaluated (180° peel test). Specifically, our target PSAs were investigated comparing with conventional PSAs (same composition and synchronized Mw) which was synthesized through free-radical polymerization. |
