The products of photopolymerizing middle-phase microemulsions containing sodium dodecyl sulfate as a surfacant, styrene as a monomer, NaCL or NaSCN as electrolyte, and either 2-pentatol or a combination of 5-hexene-1, 2-diol and sodium styrenesulfonate as a cosurfacant were characterized by using differential scanning calorimetry, gel permeation chromatography, and scanning electron microscopy (SEM).
