Data line to define a swelling gel

First (and only) line

  1. Radius of gel particles when completely dry, radry. (Units of L.)

  2. Fully swollen radius of gel particles, raf. (Units of L.)

  3. Number of gel particles per unit volume, ka. (Units of L−3.)

  4. Relaxation time constant for long-term swelling of gel particles, τ1. (Units of T.)
