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.

Spacered urea (meth)acrylates

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.

One pot synthesis of urea (meth)acrylates

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 Ris 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:

Preparation of (meth)acrylic acid esters

The invention relates to a method for preparation of (meth)acrylic acid esters from (meth)acrylic acid anhydrides. The method involves: reacting a (meth)acrylic acid anhydride of Formula (I):

A process produces a (meth)acrylate ester mixture. The process includes reacting a glycerol formal isomer mixture with an alkyl (meth)acrylate in the presence of a catalyst.
