Abstract

We present small-angle X-ray scattering measurements in model star homopolymer melts with high functionality, revealing liquid-like ordering. Monte Carlo simulations attribute this structure to the nonuniform intramolecular segmental mass distribution, which results in core-shell topology. This ordering is also reflected in their linear viscoelastic response as a new structural mode at low frequencies, due to cooperative rearrangements of the stars.
