As a primary molecular interaction governing unique phenomena found in nature, hydrogen bonding (H-bonding) has played a significant role in the design of functional polymeric materials. We herein present the design and synthesis of poly(glycidoxy phthalate) (PGP) carrying carboxylic acid group from the topology controlled polyglycidols (PGs) to induce intramolecular and intermolecular H-Bonding. In our previous studies, we successfully obtained topology controlled PGs such as branched cyclic PG and hyperbranched PG by metal-free cationic ring opening polymerization (CROP). Thus, in this work, the high level synergistic interplay between the intermolecular and intramolecular H-bonding in the PGP chains was demonstrated with stronger adhesion properties in the bulk state compared with varying topologies. The obtained PGPs were characterized by DSC, GPC, and NMR analysis and adhesion properties were analyzed by UTM.
