In contrast to the main tendencies known for truly macroporous copolymers, the dilution of initial linear polystyrene solutions was observed to have no dramatic influence on the apparent inner surface area of hypercrosslinked polymers. The surface area rather shows a tendency to decrease with dilution, contrary to the pore volume (Table 7.9). 

The replacement of one good solvent, EDC, for another good solvent, nitrobenzene or ethylene tetrachloride, used to synthesize hypercrosslinked polymers, exerts no influence upon the apparent inner surface area of the resulting networks. However, the synthesis of hypercrosslinked
