Molecular aggregation for these surfactants is different to that observed with conventional single tail surfactants. As expected, In the same context, the relation between log R p vs. The theoretical N p value has been calculated considering the head group Scheme 1: surface area of the pyridinium ring This result is certainly related to the length of the amphiphile but it is also related to the hydrophile-lipophile balance of the molecules which decreases at longer alkyl chain lengths. By Ola Karlsson. The same rules and comonomer pairs that exist in radical polymerization operate in emulsion polymerization.We report the use of these surfactants in the emulsion polymerization of styrene. Results are discussed in terms of the length of the alkyl chain and the concentration of surfactants. In order to compare with the use of a classical surfactant we also report some results obtained with dodecylpyridinium bromide.
