Abstract: Crosslinking of polymer molecules can lead to phase separation in systems composed of a polymer and diluents. The conditions for incipient phase separation and postseparat ion equilibria are described in terms of statistical theories of rubber elasticity and polymer solutions. Conditions are specified under which demixing is controlled predominantly by polymer —diluent interactions or by the presence of crosslinks and related to structural parameters of the system and advancement of the crosslinking reaction. Examples of phase separation in poly(2-hydroxyethyl methacrylate) and polystyrene gels are given.
