The present invention relates to a resin composition including a substance capable of reacting reversibly with a carbon dioxide gas, and a hydrocarbon-based polymer; a carbon dioxide gas separation membrane obtained from the resin composition; a carbon dioxide gas separation membrane module including the separation membrane; and a carbon dioxide gas separation apparatus including at least one type of the module.

The invention relates to fluoropolymer filament for use in 3-D printing, and 3-D printed fluoropolymer articles having low warpage, excellent chemical resistance, excellent water resistance, flame resistance, and good mechanical integrity. Additionally, the articles of the invention have good shelf life without the need for special packaging. In particular, the invention relates to filament, 3-D printed polyvinylidene fluoride (PVDF) articles, and in particular material extrusion 3-D printing. The articles may be formed from PVDF homopolymers, copolymers, such as KYNAR® resins from Arkema, as well as polymer blends with appropriately defined low shear melt viscosity. The PVDF may optionally be a filled PVDF formulation. The physical properties of the 3-D printed articles can be maximized and warpage minimized by optimizing processing parameters.

The present invention relates to a composition comprising particles of at least one 1,1-difluoroethylene (VDF)-based fluoropolymer, in admixture with a stabilizer agent selected from alkaline metal hydrogencarbonates or hydrogenphosphates, and to uses of said composition notably in electrochemical cells.

The invention relates to a method for preparing polyarylethersulfone-polyalkylene oxide block copolymers (PPC) comprising the polycondensation of a reaction mixture (R.sub.G) comprising the components: (A1) at least one aromatic dihalogen compound, (B1) at least one aromatic dihydroxyl compound, (B2) at least one polyalkylene oxide having at least two hydroxyl groups, (C) at least one aprotic polar solvent and (D) at least one metal carbonate, where the reaction mixture (R.sub.G) does not comprise any substance which forms an azeotrope with water.

A hybrid silicone composite for high temperature insulation applications is disclosed. The hybrid silicone composite is formed of a mixture of liquid high consistency silicone rubber and solid high consistency silicone rubber and a thermally decomposable inorganic filler which are compounded together. The compounded material is then injection molded, over molded, compression molded, cast, laminated, extruded, calendered, adhered or dispensed. When the silicone composite is exposed to a high temperature, it forms an inorganic composite and maintains its insulating properties and dimensional stability.

This disclosure relates to ingredients which are added to liquid paint, or coated onto dried paint, to provide benefits beyond the usual characteristics of commonly available water-based paints. More specifically, the disclosed chemistry changes the properties of the film created after application of the paint making the film harder and having anti-static properties.

A method for producing a vinyl chloride-based polymer, wherein the vinyl chloride-based polymer is produced by sequentially adding a first emulsifier and a second emulsifier, which are different from each other, during polymerization and using a succinate compound as a first emulsifier. The method provides improved processability by achieving low-viscosity properties when plastisol is mixed using the produced polymer, and improved fogging properties by suppressing generation of volatile organic compounds.

A method and a system for preventing water production in subterranean formations are provided. An exemplary system disclosed a water shutoff material for a wellbore. The water shutoff material includes a gel formed from an acidic suspension of nanosilica particles and an activator.

A seed coated with a seed grind, and optionally a source of sugar, a source of bicarbonate, and/or a source of fertilizer nutrient to supply plant roots with additional uptake-available carbon and energy to promote rapid growth. A method of coating seeds with the coating and a method of growing plants from the coated seed.

A method of creating a processable water soluble polymer, the method comprising the steps of: extruding a water soluble polymer composition from an extruder barrel without use of a die, wherein the extruder barrel is not vented other than via its extruder outlet, to produce an irregularly shaped polymer extrudate; directing the irregularly shaped polymer extrudate onto a chilled conveyor to cool the irregularly shaped polymer extrudate to below 60° C.; and granulating the irregularly shaped polymer extrudate to form a granulate.
