Resumen:
Abstract The aggregation of two
polymerisable surfactants dodecylethylmethacrylatedimethylammonium
bromide (C12PS) and
hexadecylethylmethacrylatedimethylammonium
bromide (C16PS) was
studied with a battery of methods.
Both surfactants form premicelles
at low concentration, and show a
critical micelle concentration and a
transition between spherical and
rod-like micelles. The micelle ionization
degree and the adsorption
at the air/solution interface were
also studied. Results are interpreted
on the basis of the conformation of
the polar head group.
