Abstract: A process for purifying ethylene cyanohydrin involves incubating an industrial grade ethylene cyanohydrin product with at least one titanium(IV)alkoxide. Ethylene cyanohydrin products with purities of >99% contain less than 0.05% of ethylene glycol (EG), and/or contain a water content of less than 1000 ppm.

Abstract: A reactive diluent system for composite resins contains a reactive diluent composition, which contains an organic phosphorus compound, and an accelerator system. The accelerator system contains at least one iron salt or complex, at least one transition metal salt or complex selected from cobalt and copper, and optionally at least one solvent.

Abstract: An improved process can be used for preparing vanillin (meth)acrylates and derivatives or structurally related compounds thereof in high purity, by reacting an alcohol with an activated (meth)acrylic acid derivative. Ethyl vanillin (meth)acrylate provides for improved room temperature crosslinking efficiency and is particularly suitable for paints/varnishes and coatings.

Abstract: A one-pot synthesis of polymerizable and acyclic urea (meth)acrylates, preferably mono(meth)acrylates, can be performed via in-situ synthesis of urea alcohols or amines followed by direct reaction with a (meth)acrylate reactive diluent. The urea alcohol/amine is obtained from isocyanates and alcohols, amines, or hydroxyamines. Subsequently, the reaction with the (meth)acrylate reactive diluent takes place and the urea (meth)acrylate is directly obtained either in solution with the reactive diluent, or as a pure material after removal of the reactive diluent.

Abstract: A novel urea (meth)acrylate can be prepared by a process involving reacting a urea containing alcohol or amine with a (meth)acrylate, (meth)acryloyl chloride, (meth)acrylic acid, or (meth)acrylic anhydride. A binder composition includes at least one repeating unit derived from the urea (meth)acrylate. The binder composition can be used in adhesive and coating applications.

Abstract: The invention relates to a method for producing glycerol mono(meth)acrylate from 2,2-dimethyl-1,3-dioxolan-4-ylmethyl (meth)acrylate by acid-catalysed reaction with methanol.
