Highly branched “bottlebrush” polymers are a class of macromolecules characterized by
side chains that are densely grafted from a backbone that is typically linear. Their unique …

Ring polymers are a unique class of macromolecules that lack free ends and show
qualitatively different dynamics compared to linear chains. Despite recent progress, the …

Ring polymers exhibit unique flow properties due to their closed chain topology. Despite
recent progress, we have not yet achieved a full understanding of the nonequilibrium flow …

Hydrodynamic interactions can dramatically influence the dynamics of fully flexible, ring-
shaped polymers in ways unknown for any other polymer architecture or topology. Tumbling …

We perform computer simulations of mechanically linked (poly [2] catenanes, PC) and
chemically bonded (bonded rings, BR) pairs of self-avoiding ring polymers in steady shear …

The dynamics of branched polymers in semidilute solutions are thought to depend on a
coupling between polymer chain architecture, intermolecular excluded volume interactions …

We use Brownian dynamics (BD) simulations and single molecule experiments to
investigate the influence of topological constraints and hydrodynamic interactions on the …

Based on the novel viewpoint that ring polymers, with their closed-loop molecular geometry,
are naturally defined by an intrinsic two-dimensional topological surface, we analyzed the …

We examined the general rheological characteristics of short-chain branched (SCB) ring
polyethylene (PE) melts using atomistic nonequilibrium molecular dynamics (NEMD) …

We present a detailed analysis of the rheological behavior of entangled short-chain-
branched (SCB) ring polymers at interfaces via direct comparison with the corresponding …
