Partial free-draining

{
  "id": "MLC-T-CHM-008484",
  "term": "Partial free-draining",
  "field": "Chemistry",
  "definition": "A hydrodynamic condition for a polymer coil in solution where the solvent molecules can partially penetrate and flow through the coil, but not entirely unimpeded. This behavior lies between the free-draining limit, where solvent flows completely through, and the non-draining limit, where the coil acts as an impermeable sphere. The extent of partial free-draining depends on the polymer's flexibility and solvent quality.",
