Abstract:

The lamellar liquid crystalline LLC regions of sodium oleate NaOL water hexadecane4-allyl-1,6-heptadiene-4-ol AHD-ol system and sodium oleate NaOL water hexadecanepentaerythritol triacrylate PETA system were determined when the weight ratio of NaOL to hexadecane was kept at 9010. Copolymerization was accomplished in the LLC phases of the above systems. AHD-ol and PETA acted as the cross-linking agents between the double bonds on NaOL backbones in their systems respectively. Interlayer spacing determinations showed that the cross-linking agents, AHD-ol and PETA, were solubilized in the middle of the NaOL hydrocarbon chains in each LLC system. As a result, the copolymerization reactions were confined within each monolayer of the amphiphilic bilayer. The systems after the copolymerization were a mixture of water and LLC phase for the former system and a mixture of LLC phase and solid particles for the latter one. The aqueous solutions of copolymers exhibited surface activity, but with both higher CMC and surface tension values than NaOL aqueous solutions.
