The discussion centers on the relationship between volume swelling and weight gain in crosslinked polymers when immersed in a solvent. It questions whether the volume swell ratio can be simply calculated using the formula (delta V) = (delta w)/density. The conservation of mass is emphasized, noting that the new polymer mass becomes Wp + w. Additionally, the new polymer volume is expressed as Vp + w/rho_s. Understanding these relationships is crucial for accurately predicting polymer behavior in solvent environments.
