The helical polyamino acids exhibit a two-component temperature-composition phase diagram that corresponds well in overall appearance to the Flory prediction for rigid, impenetrable rods. The phase diagram may be characterized as a narrow, typically

Dynamic light scattering has been used to study the diffusion of polystyrene (PS) latex spheres (≈0.2 μm radius) in poly(methyl methacrylate) (PMMA) solutions at 25 °C. The weight-average molecular weight of the PMMA was 350 000. The sign and mag

The diffusion of highly cross-linked polystyrene latex spheres of radii 0.152 and 0.208 μm through solutions of poly(γ-benzyl-l- glutamate) (PBLG) has been studied by dynamic light scattering (DLS). The solvent used was dimethylformamide (DMF), in

Dynamic light scattering has been used to follow the tracer diffusion of polystyrene spheres (R200 nm) in dilute, semidilute, and entangled solutions of poly(vinyl methyl ether) (M w = 1.3×10 6 ). Over this range of matrix concentrations, 0 ≤ c[η

We have studied the spreading of aqueous mixtures of six different silicone surfactants on Parafilm, a hydrophobic surface. Two of the surfactants were soluble in water and did not superspread. The other surfactants were insoluble and their aqueous d

The diffusion of highly cross-linked, nearly monodisperse polystyrene latex spheres of 0.2-μm radius in the presence of linear polystyrene as the matrix polymer in the moderately good solvent DMF at 25°C was determined by quasi-elastic light scatte

The translational self-diffusion coefficient of a solvent (D) in two rodlikepolymer/solvent systems, poly(benzyl glutamate) in dimethylformamide (PBLG/DMF) and poly(n-butyl isocyanate) in benzene (PBIC/benzene), was measured by pulsed gradient spin e

The diffusion of optically dense, charge stabilized, polystyrene latex spheres of 500 nm radius in water at 25°C was determined by diffusing wave spectroscopy in the backscattering mode. The diffusion coefficient of the latex spheres had a value of

Artifact-free electron micrographs and rheological properties of aqueous solutions of cetyltrimethylammonium chloride (CTAC) with salicylate (from NaSal) as the binding counterion, are presented as a function of counterion concentration.

Poly (n-butylisocyanate)-benzene solutions prepared by solubilization at 45°C, followed by aging at room temperature were found to be metastable for months, although, eventually, they separated into a birefringent polymer-rich phase and an isotropic
