semi-dilute solution

https://doi.org/10.1351/goldbook.12228
Polymer solution in the concentration range at which the domains occupied by the dissolved macromolecules or entities start to overlap.
Note: The semi-dilute solution behaviour sets in at concentrations larger than the overlap concentration, \(c^{\ast}\).
