The invention relates to a method for preparing an epoxy prepolymer composition comprising glycidyl ethers, said method comprising the following steps: a) placing a dianhydrohexitol into contact with another alcohol so as to obtain a composition of alcohols; b) reacting the composition of alcohols obtained in step a) with an epihalohydrin so as to obtain a reaction mixture comprising glycidyl ethers; c) recovering the epoxy prepolymer composition comprising glycidyl ethers from the reaction mixture obtained at the end of step b);
The invention also relates to an epoxy prepolymer composition that can be obtained by said method, a curable composition comprising said epoxy prepolymer composition, a polyepoxide obtained by curing said curable composition and a composite material, coating or adhesive comprising said polyepoxide.

The present technology relates to an ionic polymer comprising at least one repeating unit comprising the reaction product between at least one compound comprising at least two functional groups and a metal bis(halosulfonyl)imide for use in electrochemical applications, particularly in electrochemical accumulators such as batteries, electrochromic devices and supercapacitors. The present technology also relates to a polymer composition, a solid polymer electrolyte composition, a solid polymer electrolyte, an electrode material comprising said ionic polymer. Their uses in electrochemical cells and electrochemical accumulators as well as their manufacturing processes are also described.

A photosensitive resin composition including a polyimide resin (A) having a specific structure and a weight average molecular weight of 70000 or less is provided.

Compositions and methods related to the synthesis and application of poly(aryl ether)s are generally described.

A silane-modified polyphenylene ether resin and a preparation method thereof are provided. A polyphenylene ether resin having hydroxyl groups at both ends is reacted with a silane having at least one alkoxy group and at least one vinyl group at the end, so as to obtain the silane-modified polyphenylene ether resin with a vinyl group at the end.

A unique transport stabilizing combination for stabilizing items during conditions of movement comprises a viscoelastomeric thermoset overlay disposed upon a vehicular support member. The viscoelastomeric thermoset overlay component of the transport stabilizing combination is desirably viscoelastomeric, adhesive, cohesive, releasable, antipathogenic, cleansable and/or reusable. The vehicular support member is desirably an extension of a vehicle, and the transport stabilizing combination can stabilize a portable item against movement and damage during conditions of movement, such as rocking or during transport.

The invention provides a unique thermoset viscoelastomeric reaction product and a container combination comprised of the supportive base equipped with a thermoset viscoelastomer reaction product possessing unexpectedly superior adhesive and cohesive efficacy rendering it especially useful as an adhesive insert in a container combination. The thermoset insert bonds to any suitable supportive structure. The unique viscoelastomeric reaction product inserts adhesively immobilize items placed thereupon and adhesively or permanently bonds to most conventional containers. The tenacious cohesive and adhesive features of the insert allows for inverted stowage of stowed items. Due to the confining adhesive and cohesive attributes of the insert, structural supports of a flexible or solid base without a conventional confining structure provide a unique container combination for the stowed items. Containers equipped with the unique insert also surprisingly provide an aseptic environment especially useful for hygienic applications.

The present disclosure is related to an accelerator composition for the cure of polyfunctional isocyanates with epoxy resins comprising (a) a boron trihalide-amine complex, and (b) a quaternary ammonium or phosphonium halide as well as the use of such accelerator composition, cured isocyanate-epoxy resin products obtainable therefrom and a method of making a cured isocyanate-epoxy resin product.
