“…However, any expansion of the permanent or the collapsed pores is not a separate course, it must be accompanied by either the deformation of the gel phase or the relaxation of the crosslinked network chains. This is because the gel phase of the porous copolymers, as we know, is composed of highly crosslinked microgel particles that are closely linked together by less crosslinked networks to form a continuous phase 14–17. Therefore, there must be some driving forces that cause the hydrophobic porous resins to increase their volume on taking up the water.…”

“…As a porous copolymer, the swelling of the EGDM/DVB resins is a very complex process that must be discussed by considering the expansion of the permanent pores, and the “reopening” of the collapsed pores 12–14. However, the gel phase of the porous copolymers, as we know, is composed of highly crosslinked microgel particles that are closely linked together by fewer crosslinked networks to form a continuous phase 15–18. In this case, any expansion of the permanent or the collapsed pores is not a separate course, and it must be accompanied by either the deformation of the gel phase or the relaxation of the crosslinked network chains.…”

“…Direct spectroscopic support for a heterogeneous gel phase has recently been reported. 13 The sum of the products of volumes and polymer chain concentrations C in individual swollen polymer fractions in a polymer (data in Table 111) has the physical meaning of the length of polymer chains "visible" by ISEC. It has been shown that this interpretation of the values corresponds to the physical meaning reasonably well.'…”
