Abstract

Novel acrylic acid (AA) and butyl acrylate (BA) type block polymers were synthesized by living radical polymerization and evaluated their pressure sensitive adhesive performances. AA/BA/AA type triblock copolymers have good adhesive performances and holding power even without cross-linking. According to TEM pictures, micro-domain structures were observed for these triblock copolymers. These micro-domain structures may contribute to the high holding power for adhesive samples, since it was thought that the AA block micro-domains generated the hydrogen bonding power.
