The discussion centers on the relationship between volume swelling and weight gain in crosslinked polymers when immersed in a solvent. It establishes that the volume change (delta V) can be calculated using the formula (delta V) = (delta w)/density, where density is defined as the mass of the solvent divided by its volume. The key variables involved include the initial polymer volume (Vp), initial polymer weight (Wp), solvent volume (Vs), solvent weight (Ws), and their respective densities (rho_p and rho_s).
