Spacer fluids that are stable at temperatures up to at least 300 DEG C comprise water, polystyrene sulfonate and a mixture of particulate materials. The particulate materials may be chosen such that the mixture has at least a trimodal particle-size distribution. The fluids may further comprise inorganic clays, mutual solvents and surfactants.

PURPOSE: A coating composition has excellent antistatic performance and electric conductivity and forms a coating film with extremely low surface resistance. CONSTITUTION: A coating composition contains an aniline terminal-containing water-dispersible polyurethane and poly-3,4-ethylene dioxythiophene/polystyrenesulfonate. The mixing ratio of the aniline terminal-containing water-dispersible polyurethane and the poly-3,4-ethylene dioxythiophene/polystyrenesulfonate is 1:0.1-0.3 (w:w). The poly-3,...

When measuring the molecular mass distribution of conductive aniline polymer of formula (1) by GPC and converting its retention time into molecular mass (M) in terms of sodium polystyrene sulfonate, for the molecular mass (M), the area ratio (X/Y) of the area (X) of a region of 15,000 Da or more to the area (Y) of a region of less than 15,000 Da is 1.20 or more. A method for producing such a polymer includes: polymerization step (Z1) where specific aniline derivative (A) is polymerized in a solu...

Cosmetic or dermatological composition, comprises (in wt.% based on their weight) xanthan (0.01-5), dehydroxanthan (0.01-5), and polystyrene sulfonate (s) (0.1-10), in a cosmetic or dermatological carrier.

Nanocapsule compositions comprising a calcium carbonate core surrounded by a bilayer or bilayers of polystyrene sulfonate and poly(allylamine hydrochloride). The poly(allylamine hydrochloride) is conjugate to a substrate, wherein the substrate is capable of being acted upon (for example cleaved) by a biomarker or enzyme associated with a disease state of interest. The nanocapsule compositions may be administered to an animal, for example a human, for the treatment of a disease state.
