Herein is disclosed an elastomeric silicone composition comprising at least a first and a second glycerol phase which are distinct from each other and a method of making the same. The elastomeric compositions are special therein that zero-order active substance release can reversibly be obtained by modifying the glycerol content of the silicone composition.

Glycerol-silicone elastomers as active matrices with controllable release profiles

The present invention relates to an elastomeric composition comprising a silicone rubber, glycerol, at least one crosslinking agent, and optionally one or more excipients, wherein said glycerol is present as discrete droplets in the silicone rubber, obtainable through the application of high shear forces.

Silicone elastomers and their preparation and use

The present invention relates to a method of providing a barrier in a fracture-containing system, comprising: i) Providing a treatment fluid comprising: a) a base fluid; b) an elastomeric material, wherein said elastomeric material comprises at least one polymer capable of crosslinking into an elastomer, and c) at least one crosslinking agent; ii) Placing the treatment fluid in a fracture-containing system; iii) Allowing the elastomeric material to crosslink with itself to form a barrier in said fracture-containing system; wherein the elastomeric material and/or the crosslinking agent are of neutral buoyancy with regard to the base fluid. The invention is contemplated to having utility not only in the oil-drilling industry but also in the plugging of fractures in sewer drains, pipelines etc.

Method of providing a barrier in a fracture-containing system

The sealing device () includes an elongated body () adapted to be introduced into a tube-shaped channel () and including a sealing fluid placement section () arranged between a first and a second annular flow barrier (). The elongated body further includes a sealing fluid activation section () arranged between the second annular flow barrier () and a third annular flow barrier () and including a sealing fluid activation device () adapted to at least initiate or accelerate curing of the sealing fluid (). In operation, the elongated body may be displaced along the tube-shaped channel until the sealing fluid activation section is placed at a position where sealing fluid has been ejected by the sealing fluid placement section, and the sealing fluid activation device may be activated. Thereby, sealing fluid may be cured at selected locations along the tube-shaped channel after ejection of sealing fluid.

Sealing device and method for sealing fractures or leaks in wall or formation surrounding tube-shaped channel

The present invention relates to an ionic interpenetrating polymer network comprising at least one elastomer and an ionic supramolecular structure comprising the reaction product of at least two chemical compounds wherein each of said compounds has at least two functional groups and wherein said compounds are able to undergo Lewis acid-base reactions. The interpenetrating polymer network may be used as dielectric electroactive polymers (DEAPs) having a high dielectric permittivity.
