Title:
ONE POT SYNTHESIS OF UREA (METH)ACRYLATES
Document Type and Number:
Japanese Patent JP2023041046
Kind Code:
A
Abstract:
To provide the one-pot synthesis of polymerizable and acyclic urea (meth)acrylates, preferably mono(meth)acrylates, via in-situ synthesis of urea alcohols or amines followed by direct reaction with a (meth)acrylate reactive diluent.SOLUTION: 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 as either solution in the reactive diluent or as pure material after removal of the reactive diluent.SELECTED DRAWING: None
