Embodiments relate to coated proppants, a method of making the coated proppants, and a method to use coated proppants in fracturing subterranean formations around oil and gas wells to improve oil recovery. The proppants are coated with an oil well treatment agent, specifically, a wax inhibitor and/or a pour point depressant composition.

Proppant comprising an oil well treatment agent coating

A novel low viscosity epoxide having the following general Structure (I): Structure (I) wherein R1 and R2 can be, but is not limited to, hydrogen or a hydrocarbon group having from C1 to about C20 carbon atoms; with the proviso that R1 and R2 are not both hydrogen. 

Epoxide compound

A curable composition comprising (a) at least one low viscosity epoxide resin compound having the following chemical structure: (I) wherein Rand Rare hydrogen or a hydrocarbon group having from 1 to 20 carbon atoms, with the proviso that Rand Rare not both hydrogen, and (b) at least one curing agent or UV photoinitiator; and a thermoset prepared from the above curable composition. 

Curable compositions and thermosets prepared therefrom

An adduct of (a) at least one divinylarene dioxide, and (b) at least one end-functionalized polymer. For example, the adduct may be beneficially used as a toughening agent for toughening thermoset resins such as epoxy resins.

Adduct

A low viscosity toughened epoxy resin formulation including a divinylbenzene dioxide as a component in the formulation; wherein the formulation is useful for the manufacture of thermoset polymers.

Toughened epoxy resin formulations

A multifunctional aromatic amine hardener composition including the reaction condensation product of (a) at least one aniline and (b) at least one non-aromatic cyclic dicarboxaldehyde; and a reactive thermosettable resin composition including (i) at least one multifunctional aromatic amine hardener composition curing agent, (ii) at least one thermoset resin, and optionally (c) at least one catalyst; and a process for preparing a thermoset product from the thermosettable composition. The hardener composition above and a thermoset resin may be used to prepare a thermoset product with improved thermo-mechanical behavior.
