Effects of PEA-(COOH)2 molecular weight (MPEA) and the blend ratio on the viscoelastic properties were investigated by rheological and small angle X-ray scattering measurements. Rubbery plateau appeared by adding PEI due to network formation with ionic hydrogen bonded crosslinks between amines on PEI and carboxylic acids on PEA-(COOH)2. The highest temperature of a storage modulus-loss modulus crossover as well as the highest flow activation energy was attained at a certain mole ratio of amines to carboxylic acids, irrelevant to MPEA, indicating optimized supramolecular networks were achieved by stoichiometric balance of two functional groups. Since telechelic PEA-(COOH)2 serves as a network strand, the plateau modulus was inversely proportional to MPEA, which was consistent with the correlation length between crosslinks estimated by X-ray scattering measurements. © 2014 Wiley Periodicals, Inc.
