Competitive interactions in ternary systems including a lightly crosslinked polyanionic hydrogel, a protonated Astramol™ poly(propylene imine) dendrimer (of first to fifth generation), and an ionic surfactant were studied. It was found that the dir

The structural properties of charged G5 poly(propyleneimine) dendrimers (Astramol) in D2O solutions have been investigated using small-angle neutron scattering. Upon addition of acid (HCl), the dendrimers become charged, and the scattered patterns ex

Investigations have been carried out to clarify the binding interactions between two kinds of native DNA: one from salmon sperm (300−500 bp) and another from bacteriophage T4dC (166 kbp) and amine-terminated, diaminobutane core, poly(propylene imin

Blends were made by solution and melt-mixing fatty-acid-modified dendrimers with various polyolefins. Small-angle neutron scattering (SANS) was used to determine the miscibility of the blends. Poly(propylene imine) (PPI) dendrimers G1, G3, and G5 [DA

Small-angle neutron scattering (SANS) has been applied to extract the single-chain form factors of the fatty acid (FA) and the dendrimer components in bulk and dilute solution of fatty acid modified poly(propyleneimine) dendrimers (Astramol). The fat

Brownian dynamics simulations of a simple model of a polymer gel were performed to investigate the conditions under which gels show nonergodicity, the presence of frozen density fluctuations which do not relax completely, and to explore possible conn

Small-angle neutron scattering has been applied for structural investigations of amine-terminated poly(propylene imine) dendrimer (Astramol) solutions in D2O as a function of concentration and acidity. The forward scattering, dΣ/dΩ(Q = 0), decrease

Fiber optic dynamic light scattering (FODLS) was used to study the kinetics of aging processes in emulsions of n-alkanes stabilized by a surfactant. The method is particularly useful for this purpose because it permits measurements in concentrated em
