Polymerization in non-aqueous lyotropic liquid crystals: Influence of the unsaturation site
Two surfactants, bis[2-(dodecyloxycarbonyl)ethyl](p-vinylbenzoyl)methylammonium chloride (SI) and bis[2-(10-undecenoyloxycarbonyl)ethyl](p-methylbenzoyl)methylammonium chloride (SII) were synthesized and copolymerized with polar and non-polar monomers to form regularly layered structures.
The results showed a pronounced difference between the two surfactants. SI with the double bond close to the polar group accepted a large number of monomers, in contrast to the behavior of SII. For SI the polymerization changed the conformation of the p-vinylbenzoyl group depending on the location of the added monomer while copolymerization of the monomers with SII gave no significant change.
A comparison with earlier results from bis[2-(10-undecenoyloxycarbonyl)ethyl](p-vinylbenzoyl)methylammonium chloride provided proof of copolymerization of all the groups.
