A monomer is provided which is excellent in reactivity, can give high heat resistance and high refractive index, and has two or more polymerizable functional groups with different polymerization properties and an aromatic ring in the molecule. An industrial advantageous process for producing the monomer is also provided. The monomer is an aromatic isocyanate compound containing a (meth)acryloyl group, and is represented by Formula (I): wherein Ris a single bond or a linear or branched alkylene group of 1 to 5 carbon atoms, Ris a hydrogen atom or a methyl group, Ris a single bond or a linear or branched alkylene group of 1 to 3 carbon atoms, X is independently a halogen atom or an electron-withdrawing group, m is an integer ranging from 0 to 4, n is an integer ranging from 1 to 3, and 1&#x2266;m+n&#x2266;5.

(Meth) acryloyl group-containing aromatic isocyanate compound and production process thereof

The invention aims to provide a method whereby (meth)acrylate derivatives having an isocyanate group can be obtained in high yield by dehydrochlorination of 3-chloropropionate derivatives having an isocyanate group under industrially advantageous and mild conditions, and the content of residual hydrolyzable chlorine can be reduced. A method for producing a (meth)acrylate derivative having an isocyanate group comprises performing dehydrochlorination of a 3-chloropropionate derivative having an isocyanate group in the presence of a basic nitrogen compound having a tertiary nitrogen, the tertiary nitrogen of the basic nitrogen compound having at least one group other than an aromatic ring group.

Method for producing (meth)acrylate derivative having isocyanate group

There are provided a novel ethylenically unsaturated group-containing isocyanate compound, a process for producing the same, and a reactive monomer produced from the isocyanate compound, a reactive polymer and its use. The ethylenically unsaturated group-containing isocyanate compound according to the present invention is represented by formula (I).
