Abstract
A method for treating solid materials is disclosed, where the treating compositions coats surfaces or portions of surfaces of the solid materials changing an aggregation or agglomeration propensity of the materials. Treating composition and treated solid materials are also disclosed. The methods and treated materials are ideally suited for oil field applications.
Claims38
(canceled)
The method of claim 34, wherein the composition forms a partial or complete coating on surfaces of the particulate solid material, surface, or structure.
The method of claim 34, wherein the composition further comprising a reaction product of an amine and phosphate-containing compound.
The method of claim 34, wherein the particulate solid material is selected from the group consisting of natural or synthetic metal oxides and/or ceramics, metals, plastics and/or other polymeric solids, solid materials derived from plants, and mixtures or combinations thereof.

A method for changing an aggregation potential or propensity of a particulate solid material comprising the step of:
- contacting the particulate solid material, a surface of a substrate or a surface of a structure with a composition including a polymer comprising homopolymers selected from the group consisting of poly-2-vinyl pyridine, poly-4-vinyl pyridine, and mixtures or combinations thereof and copolymers selected from the group consisting of copolymers of 2-vinyl pyridine and 4-vinyl pyridine, copolymers of ethylene and 2-vinyl pyridine and/or 4-vinyl pyridine, copolymers of propylene and 2-vinyl pyridine and/or 4-vinyl pyridine, copolymers of acrylic acid and 2-vinyl pyridine and/or 4-vinyl pyridine, copolymers of methacrylic acid and 2-vinyl pyridine and/or 4-vinyl pyridine, copolymers of acrylates and 2-vinyl pyridine and/or 4-vinyl pyridine, copolymers of methacrylates and 2-vinyl pyridine and/or 4-vinyl pyridine, and mixtures or combinations thereof and where the composition increases an aggregation potential or propensity and/or alters a zeta potential of the particulate solid material, the surface of the substrate or the surface of a structure.
