Abstract
Abstract New epoxy-acrylic acid esters are obtained if 3(acryloyloxyalkyl)-hydantoins are glycidylated in a known manner. The new epoxy-acrylic acid esters are viscous liquids with good processing properties. They furthermore possess a good solvent power for polymerisable monomers and can, without difficulties, be cast together with these.
