ABSTRACT:
A process for preparing a polymerizable (meth) acrylate oligomer which comprises reacting an epoxide with a carboxylic acid (or anhydride thereof), at least one of said epoxide and carboxylic acid compounds containing an unsaturated alicyclic dicarboxyl group and the other containing an acryloyl group, in the presence of a metal nitrite or N-nitroso-hydroxylamine derivative. The polymerizable (meth) acrylate oligomer containing an acryloyl and an unsaturated alicyclic dicarboxyl group in the molecule is employed in coatings, adhesives, castings and the like.
