摘要: The dynamics of supramolecular networks made up of partially hydrolyzed poly (n-butyl acrylate)[PnBA] is investigated. These linear entangled random copolymers [PnBA-AA] self-assemble via hydrogen bonding interactions between carboxylic acid groups. Two types of supramolecular assemblies are revealed, ie, binary assembly of carboxylic acid dimers and collective assembly of dimers into distinct poly (acrylic acid)[PAA] domains. The latter is proved by emergence of new relaxation processes in broadband dielectric spectroscopy …
