The influence of hydroxylic group substitution on micellar properties of polyoxyethylene alcohols
Acetates and chlorides of the polydisperse polyoxyethylene alcohols containing from 6 to 14 carbon atoms in the alkyl group and average number of 2–14 oxyethylene units were synthesized. Their critical micelle concentrations were determined using the surface tension and light scattering methods. The influence of the terminal acetyl group and chlorine atom on the products’ hydrophilicities was discussed. It was found that acetates demonstrate similar hydrophilicity as the polyoxyethylene alcohols. Chlorides are much more hydrophobic and depending upon the polyoxyethylene chain length a chlorine atom is equivalent to 2–4methylene groups.
