Compatibility and neutron scattering studies of mixtures of polystyrene with poly(2,6-dimethyl 1,4-phenylene oxide) and its brominated derivatives

Nonequilibrium Plasma Treatment of Miscible Polystyrene/Poly(phenylene oxide) Blends

“…Miscibility over the entire composition range for polystyrene/poly(phenylene oxide) blends has been known for a long time and widely investigated using a variety of techniques (e.g., glass transition temperature, neutron scattering studies, etc.). Infrared and ultraviolet spectroscopic studies have shown that this high miscibility arises from strong interactions between the phenyl rings contained in poly(phenylene oxide) and polystyrene.…”

A simple route to deuterated polystyrene block copolymers by reverse iodine transfer polymerisation

“…The most common use of deuterated polymers is to gain contrast in neutron scattering experiments. [20][21][22][23][24][25][26] Other applications include the use of deuterated compounds in pharmacology to follow metabolism, [27][28][29][30][31][32] tracing biodegradation of hydrocarbons in water 33 and the use of deuterated compounds in nuclear fusion experiments. [34][35][36] Deuterated polystyrene (d-PS) is usually synthesised using living anionic polymerisation.…”

Thermodynamic Differences Between Deuterated and Protonated Polystyrenes Evaluated Using Reversed Phase Liquid Chromatography

“…Deuterated and protonated compounds have generally been considered to possess similar chemical and physical properties to one another. Techniques such as small‐angle neutron scattering (SANS)1–4 and neutron reflectivity (NR), especially involving isotopic labelling, have become standard tools for measuring polymer solubilities, diffusion coefficients and conformations 5. These methods have exploited the large differences in neutron scattering lengths between hydrogen and deuterium nuclei to highlight or contrast particular aspects of the system or molecules 6.…”
