Abstract: A sealant composition for use in two-pane or multi-pane insulating glass or solar modules, the sealant composition including: a) an olefinic polymer having a number average molecular weight from about 100 D to about 700,000 D, preferably from about 100 D to about 300,000 D; b) a modified olefinic polymer; c) a fine-particle inert filler; d) at least one of a desiccant and a water scavenger, and e) an aging resistor. The sealant composition has a tensile strength greater than 20 PSI, preferably greater than 50 PSI, a lap shear strength greater than 20 PSI, preferable greater than 40 PSI, and the tensile and lap shear strengths balanced such that the sealant fails cohesively before failing adhesively.

Abstract: Composites containing a hydrocarbon-soluble well treatment agent may be supplied to a well using a porous particulate. Such well treatment agents may for example inhibit the formation of paraffins, salts, gas hydrates, asphaltenes and/or other deleterious processes such as emulsification (both water-in-oil and oil-in-water). Further, other well treatment agents include foaming agents, oxygen scavengers, biocides and surfactants as well as other agents wherein slow release into the production well is desired.

Abstract: This invention provides a composition and a method of using a composition containing an imidazoline, optionally containing a paraffin inhibitor, for improving the pour point of liquid hydrocarbons, such as crude oil and petroleum fuel, and/or inhibiting or reducing the formation of paraffin deposits in such liquids.

Abstract: Homopolymers and copolymers of an esterified reaction product of an epoxidized mono-hydroxyl alcohol and a free radical polymerizable monomer are highly effective demulsifying agents. The molecular weight of the polymer is between from about 10,000 to about 500,000. The epoxidized mono-hydroxyl alcohol is preferably a reaction product of a C6–C30 linear or branched alcohol and an alkylene oxide. The alkylene oxide is preferably either ethylene oxide, propylene oxide or butylenes oxide or a mixture thereof. The free radical polymerizable monomer is preferably a vinyl aromatic compound or an acrylic or methacrylic based monomer. The polymer preferably comprises a micellar assembly. Such polymers are highly effective in demulsifying crude oils having API gravities of from 8 to 28 or a crude oil having a viscosity between from about 3 to about 10,000 CPS @ at 25° C.
