abstract = {Association behavior of the biocompatible amphiphilic
cationic gradient polyelectrolyte
poly[(2-methyl-2-oxazoline)-grad-(2-phenyl-2-oxazoline)-mod-(ethylene
imine)] (HPPhMeOx) prepared by partial hydrolysis of the
gradient copolymer
poly[(2-methyl-2-oxazoline)-grad-(2-phenyl-2-oxazoline)] and
the interaction of HPPhMeOx with the anionic surfactant
sodium dodecyl sulfate (SDS) in aqueous solutions were
investigated by scattering techniques (SANS, DLS) and by
atomic force microscopy. SANS measurements revealed that
large particles with the hydrodynamic radius of ca. 500 nm
observed in HPPhMeOx aqueous solutions by DLS are formed by
a network of physically crosslinked compact hydrophobic
domains with the mean radius of ca. 10 nm. Upon addition of
sodium dodecyl sulfate (SDS), the size of the domains
increases at low amounts of the added SDS due to hydrophobic
interaction of the single surfactant ions with the
aggregates. Further addition of SDS leads to the formation
of the co-assembled polyelectrolyte–surfactant complex
manifested in SANS by the presence of the correlation peak
from the densely packed SDS micelles as well as by partial
disruption of the domains.},
