Swelling equations were derived for polymeric networks that consist of two swellable but distinct phases. These equations can be used to describe the equilibrium swelling behavior of certain two‐phase network systems. Using physicochemical measurements of the equilibrium polymer volume fraction, it was possible to calculate the number‐average molecular weight between crosslinks, M̄ c , using these equations. The influence of several structural parameters on M̄ c was investigated. © 1992 John Wiley & Sons, Inc.
