Abstract: Aqueous suspensions are presented that are stable against settling without additional mixing in which the suspensions comprise a water soluble polymer that is anionic or non-ionic comprising a blend of water with at least about 32 weight percent chloride salt with a counter ion A+a with 2?a, from about 1 wt % to about 10 wt % particulate polyethylene glycol having an average molecular weight from about 1600 g/mol to about 50,000 g/mol, and from about 10 wt % to about 50 wt % of the water soluble polymer that is not a poly ether. The suspension has chlorides in a sufficient amount to inhibit hydration of the suspended water soluble polymer and the particulate polyethylene glycol. The aqueous suspension can be formed by adding a powder of polyethylene glycol to a high salt solution and then adding the high molecular weight polymer. The aqueous suspensions can be useful as friction reducing agents in flowing liquids, such as for hydraulic fracture.

Abstract: Powder blends are described comprising blends of particulate water soluble high molecular weight polymer flocculants. The polymer flocculants can include polyethylene oxide, polyacrylamide, copolymers thereof and combinations thereof. The powder blends allows the use of fine powders while reducing potential air quality and safety issues. The powder blends can be used for waste water purification, fiber dewatering, and the like. The powder blends can be diluted by a water dilution flow prior to entering a waste water stream.

Abstract: Stable dispersions of solid polyethylene glycol particles are described in polyalkylene glycol liquids. The stable dispersions have an increased viscosity relative to the liquids without the suspended particles. The stable dispersions can be formed from a melt of the polyethylene glycol particles mixed within the liquid.

Abstract: Polymer flocculants are described comprising blends of high molecular weight polyethylene oxide and high molecular polyacrylamides. When introduced in desired amounts and with desired molecular weight ranges, excellent flocculation function is found that can be used to reduce polymer consumption to obtain a desired purity of clarified waste water. It has been found that the desirable polymer blends can be effectively added upstream from locations in which polyethylene oxide would generally be added so that the polymer blend can effectively mix with the slime flow to reduce or eliminate the need for excess polymer use to compensate for less effective mixing with the slime flow. Suitable waste treatment systems are described to provide for the delivery of the flocculants in the waste treatment process.

Abstract: Flowable liquid suspensions are described comprising blends of particulate water soluble high molecular weight polymer flocculants. The polymer flocculants can include polyethylene oxide, polyacrylamide, polyDadmac, Dadmac-acrylamide copolymers, copolymers thereof and combinations thereof. The suspension allows the use of fine powders while reducing potential air quality and safety issues. The suspensions generally settle when mixing is stopped, but a uniform dispersion results when the suspensions are mixed, and the mixed suspensions can be delivered for use. The flocculant suspensions can be used for waste water purification, fiber dewatering, and the like.

Abstract: Dispersions of superabsorbent polymers are described comprising blends of polyols and super absorbent polymer. Products comprising deposits formed from such dispersions are also described. Suitable polyols can include, for example, polyethylene glycol. The dispersions can be flowed onto an absorbent sheet to form a deposit (sheeted SAP), which in some embodiments can be along a fraction of the sheet surface. Generally, the deposits are dried through a wicking process in which the polyol is wicked away from the superabsorbent polymer. The sheeted SAP can be incorporated into a final product with the deposit secured within the product. The dispersion allows for selective placement of superabsorbent polymer onto an absorbent sheet and/or in a final product. Embodiments based on coated yarns and the like are also presented.
