Abstract

A reactive amine accelerator is prepared by reacting a primary or secondary aromatic amine with a diglycidyl ether and an α,β-unsaturated carboxylic acid. The reactive amine accelerator can be used in a reactive resin, in particular based on an epoxy (meth)acrylate resin or a urethane (meth)acrylate resin. A reactive resin composition, in particular based on epoxy (meth)acrylate resin and urethane (meth)acrylate resin, which has an amine accelerator is useful. The amine accelerator is covalently incorporated into the polymer network.
