PROCESS FOR THE PREPARATION OF EPOXY RESIN HARDENERS

摘要

A process for the preparation of epoxy resin hardeners based on complex of triethylbenzylammonium chloride with zinc chloride which is prepared by condensation of benzyl chloride with triethylamine. Further interaction of the prepared ammonium quaternary salt with zinc chloride is carried out directly in the medium of reactive diluents at temperature of 70-90 °С.
