Unexpected thermal characteristics of aqueous solutions of poly(2-isopropyl-2-oxazoline)

Abstract

Annealing of dilute aqueous solutions of poly(2-isopropyl-2-oxazoline) at above the cloud point leads to the irreversible formation of coagulate particles with hierarchical ordering on two length-scales: micron-sized assemblies of fibrils that measure tens of nanometres across.
