Abstract: The present invention relates generally to water soluble polymer powder formulations, and more particularly, to a cellulose ether formulation which in powder form is suitable for direct addition to water-based systems to produce smooth, lump free solutions. The cellulose ethers are crosslinked with an aldehyde crosslinker and include a dry weak acid which slows hydrolysis of the hermiacetal linkage formed by the crosslinker. The selected acid does not adversely affect solubility stability.

Abstract: The viscosity of solutions of nonionic synthetic associative thickeners is controlled by adding organophosphates to the solution of associative thickeners. The associative thickeners are hydrophobically modified polymers and the organophosphates include one or more hydrophobic groups.

Abstract: The presently disclosed and/or claimed inventive concept(s) relates generally to a cementing fluid for use in high temperature wellbore application. More particularly, the presently disclosed and/or claimed inventive concept(s) relates to a cementing fluid comprising an aqueous fluid, a hydraulically-active cementitous material, and a suspending agent, wherein the suspending agent is a high molecular weight hydrophobic copolymer or a cross-linked hydrophobic copolymer particulate. Additionally, the presently disclosed and/or claimed inventive concept(s) relates generally to the methods of making the cementing fluid containing the suspending agent.

Abstract: The presently disclosed and claimed inventive concept(s) relates to a method for making a particular product comprising a nonionic synthetic associative (NSAT) rheology modifier and a dissolution promotion water soluble additive. The method comprising the steps of: (a) obtaining the NSAT theology modifier and the dissolution promotion water soluble additive; (b) melting the NSAT theology modifier and the dissolution promotion water soluble additive; (c) mixing the molten NSAT theology modifier and the dissolution promotion water soluble additive; and (d) producing the particulate product from step (c). The NSAT rheology modifier is selected from the group consisting of hydrophobically-modified ethoxylated urethane (HEUR), hydrophobically-modified polyethylene glycol (HMPEG), and hydrophobically-modified polyacetal-polyether (HMPAPE). The particulate product prepared from the method is incorporated into a waterborne paint formula.

Abstract: A synthetic polymer has a water-soluble or water-swellable polyurethane backbone and terminal groups and/or intermediate groups of blocks of hydrophobes of alkyl- or aryl compounds containing a polymerizable cyclic monomer or a polymerizable double bond (or alkene) group or derivatives thereof. The blocks of hydrophobes are composed of two or more units of the same or different hydrophobes. These synthetic polymers are used as rheology modifiers, especially in latex paints.

Abstract: This invention relates to non-uniformly substituted (“blocky”) hydroxyethylcelluloses (HECs) and derivatives thereof that exhibit associative behavior in both neat solutions and in filled systems. The HECs and derivatives thereof exhibit unique and highly desirable rheology and are more efficient in thickening aqueous systems than prior art HEC products. These blocky HECs can be distinguished from prior art and commercial HEC products by having an unsubstituted anhydroglucose trimer ratio (U3R) greater than 0.21 and the hydroxyethyl molar substitution greater than about 1.3 and less than about 5. This invention also relates to processes for making blocky HEC and uses thereof in functional systems.

Abstract: An oilfield servicing fluid composition containing an aldehyde guar produced by enzymatic oxidation of a non-derivatized, straight guar or of a guar derivative. The enzyme used to oxidize the guar to the aldehyde guar is galactose oxidase, which may be combined with catalase or catalase and peroxidase. The aldehyde guar is useful as an effective gelling agent for oilfield servicing fluids such as hydraulic fracturing fluids and stimulation fluids.

Abstract: An aqueous dispersion includes an associative thickener based on a hydrophobically modified poly(acetal- or ketal-polyether) (HM-PAPE) and at least one viscosity reducing agent selected from ethoxylated alcohols, ethoxylated acetyleneic diols, phosphate esters, dialkyl sulfosuccinates, and mixtures thereof. This aqueous dispersion improves the incorporation of the HM-PAPEs into aqueous based protective coatings. This dispersion also improves water-borne coating compositions that optionally contain latex.
