Alcohol-modified polyepoxides, their preparation and their use in curable mixtures

摘要

This application discloses a synthetic resin based on alcohol-modified polyepoxides. The synthetic resin can be prepared by reacting a diepoxide, or a mixture of diepoxides, having an epoxide equivalent weight of less than about 500, with compounds with a hydroxyl group, which is reactive towards epoxide groups, in a molar ratio from about 2:1 to about 7:6 at temperatures from about 100 DEG C. to about 180 DEG C. in an organic solvent free of hydroxyl groups. The synthetic resin has terminal epoxide groups and a mean molecular weight from about 400 to about 5000.
