  • Patent number: 11958800
    Abstract: The invention relates to a method for preparation of (meth)acrylic acid esters from (meth)acrylic acid anhydrides. Wherein the method for preparation of the (meth)acrylic acid ester, comprises at least step (a) as follows: (a) reacting a (meth)acrylic acid anhydride of Formula (I): wherein R1 is a hydrogen atom or a methyl group; with a substrate in the presence of a first catalyst to form a product mixture comprising the (meth)acrylic acid ester; and wherein: the substrate is selected from the group consisting of: primary alcohols; secondary alcohols; tertiary alcohols; and phenols; and the first catalyst comprises a salt of magnesium or of a rare earth element.

  • Publication number: 20230365487
    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.

  • Publication number: 20230101100
    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.

  • Publication number: 20230088931
    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.
