Abstract
The invention relates to the process for the preparation of liquid reaction products of cycloaliphatic epoxides with mono- or multifunctional hydroxy compounds. The process comprises reacting a polyfunctional cycloaliphatic epoxy resin with a mono- or multifunctional hydroxy compound in the presence of a heterogeneous surface-active catalyst. The invention also relates to curable compositions containing the product obtained by the process.
