Acid-containing polymer chain dynamics
Work by Amalie Frischknecht (Sandia), Karen Winey (U Penn), and coworkers to understand chain dynamics in precise acid-containing polymers.
The journal cover shows the comparison of quasi-elastic neutron scattering (QENS) and atomistic molecular dynamics simulations for poly(ethylene-co-acrylic acid) polymers that have acid groups spaced every 21 carbons along the polyethylene backbone. The simulation snapshots show the movement of acid groups from one aggregate to another over approximately 1 ns.
