Abstract

Disclosed is a method for producing vinyl ester urethane resins, in which a dianhydrohexitol-compound is reacted with a diisocyanate in the presence of a monomeric radically co-polymerizable compound as a solvent and the product is reacted with a hydroxy-substituted (meth)acrylate. As a result, vinyl ester urethane resins based on dianhydrohexitol-compounds and also based on renewable raw materials can be obtained in a simple manner with high yields. The resins are suitable as binding agents in chemical fixing engineering.
