摘要:
A binder composition for a rechargeable lithium battery includes a semiinterpenetrating polymer network (semi-IPN) comprising a copolymer and a polyacrylamide; wherein said copolymer comprises a repeating unit represented by the following Chemical Formula 1 and a repeating unit represented by the following Chemical Formula 2.
In Chemical Formula 1, R 1 and R 2 are the same or different and are independently selected from hydrogen, or a substituted or unsubstituted C1 to C10 alkyl group, and R 3 and R 4 are an alkali metal. In Chemical Formula 2, R 5 to R 8 are the same or different, and are independently hydrogen, a substituted or unsubstituted C1 to C30 alkyl group, a substituted or unsubstituted C6 to C30 aryl group, or a substituted or unsubstituted C1 to C30 alkoxy group.
摘要:
The present invention relates to a dental hydrogel and to a method for manufacturing same, and more particularly, to a hydrogel and to a method for manufacturing same wherein the hydrogel, which can be freely used during treatment irrespective of the shape of a bone defect region, has a decomposition rate capable of being regulated in situ and can thus be rapidly decomposed over a certain time, i.e., after the completion of bone regeneration. Furthermore, the present invention relates to a hydrogel membrane using the hydrogel which can be applied to a bone defect region irrespective of the shape thereof, and to a method for manufacturing same.

Embodiments of the present disclosure include a method for treating a subterranean formation including injecting into the subterranean formation a fluid composition that includes a fluid and a deformable proppant having an interpenetrating polymer network formed from a first polymer component and a second polymer component.
摘要:
An interpenetrating polymer network (IPN) adhesive comprises an acrylated polymer system curable by radiation, and a flexible epoxy system thermally curable after the acrylated polymer system is cured.
摘要:
A hydrogel of the semi-interpenetrating network structure or interpenetrating network structure, characterized in that the hydrogel is one formed from a first monomer ingredient at least 10 mol% of which is accounted for by a charge-possessing unsaturated monomer and a second monomer ingredient at least 60 mol% of which is accounted for an electrically neutral, unsaturated monomer, the molar ratio of the first monomer ingredient to the second monomer ingredient being from 1/2 to 1/100, and that the second monomer ingredient has been polymerized and crosslinked to a lower degree of crosslinking than the first monomer ingredient The hydrogel is usable in a diaper, sanitary good, sustained-release agent, construction material, building material, communication material, soil conditioner, contact lens, ocular lens, hollow fiber, artificial cartilage, artificial organ, material for fuel cells, battery diaphragm, impact-resistant material, cushion, etc.
摘要:
Novel compositions consisting of semi-interpenetrating network of cross-linked water soluble derivatives of basic polysaccharides and a non-cross-linked component, which is an anionic polysaccharide are provided. Methods for the production of such compositions are also disclosed. Preferably the basic polysaccharide is chitosan or a derivative thereof and the anionic polysaccharide is hyaluronic acid. The compositions can be formed into gels or films, for example, and thus find use in a wide range of medical applications in the fields of dermatology, plastic surgery, urology and orthopaedics.
摘要:
The invention relates to a thermoplastic composition, comprising a polyamide and/or polyester matrix and differing additives. Said composition has a high fluidity thus making suitable the use of different techniques for forming in the molten state, such as moulding, injection moulding, extrusion and drawing. Said composition particularly permits the production of moulded plastic articles with good mechanical properties and an improved surface appearance.
