Abstract: Polymer matrix particles useful for inhibiting scale formation in oil and gas wells are described. The insoluble, porous, crosslinked polymer matrix includes a polymer backbone and ionic functional groups covalently bonded to the backbone, the ionic functional groups being capable of selectively attracting and binding salt scale-forming ions when in contact with a liquid containing such ions.

Abstract: Decontamination compositions useful to decontaminate potentially toxic materials, such as PAH and others, present on clothing comprise an aqueous solution of a water soluble cerium salt or a dispersion of cerium oxide in water. The decontamination composition may optionally include at least one of an oxidizer, a surfactant, a co-solvent, a chelating agent, and a polymer. Methods of decontaminating clothing involve applying the decontamination composition to the clothing.

Abstract: In a method of producing a polymer composite, a polymer is provided in a liquid state such as a molten state. A plant material, such as soymeal, is provided that includes protein and carbohydrate. The plant material has a particle size less than 50 microns. A reactive protein denaturant is also provided. A dispersion of the plant material and the reactive protein denaturant is formed in a matrix of the liquid polymer. The plant material is reacted to bond with the reactive protein denaturant, and the reactive protein denaturant is reacted to bond with the polymer. The polymer is solidified to produce the polymer composite.

Abstract: A cationic surfactant and a method of making the cationic surfactant are described. The method comprises reacting a lipophilic bio-based material having at least one epoxy functional group and a hydrophilic organic compound having at least one cationic functional group and at least one hydroxyl functional group to form a reaction product containing a stable ether linkage connecting the lipophilic bio-based material to the organic compound. At least a portion of the cationic functional groups is neutralized or ion exchanged with an organic acid. Incorporation of the simple organic acid reduces the surfactant's aquatic toxicity and acts as a substrate to encourage co-digestion of the surfactant molecule, making the compound more biodegradable.

Abstract: Processes for producing polymer microcapsules using vicinal functional oligomers are also described. The vicinal functional oligomers can be made by polymerizing an acrylate monomer, a styrene monomer, or both in the presence of a chain transfer agent. The vicinal functional oligomers can be reacted with epichlorohydrin to form vicinal epoxies. The vicinal epoxies can be reacted with polyamines to form epoxy polymer microspheres. The vicinal epoxies can be reacted with carbon dioxide in the presence of a catalyst to form vicinal cyclic carbonates. The vicinal cyclic carbonates can be reacted with polyamines to form isocyanate-free polymer microspheres. Polymer microspheres made by the processes are also described.
