Biporous hypercrosslinked polystyrene networks

The basic tendencies of hypercrosslinked network formation in media having high thermodynamic affinity to polystyrene (e.g., EDC or nitrobenzene) are also obeyed when the post-crosslinking of polystyrene chains proceeds in a poorer solvent, such as cyclohexane [152]. Thus, the data presented in tables 7.10 and 7.17 illustrate that the properties of networks crosslinked with MCDE to 100% strongly depend on both the rate of chemical reaction of the ether with polystyrene and the extent of dilution of the latter with cyclohexane. Indeed, at a constant linear polystyrene 

II = networks were prepared by crosslinking in the mixture of EDC with n-octane. 

Similarly to the crosshnking in EDC, increasing dilution of polystyrene chains with cyclohexane reduces the extent of mutual network mesh entanglements and, therefore, significantly enhances the swelling capacity
