ABSTRACT:
This invention is concerned with water-soluble epoxy resins represented by the general formula ##STR1## wherein A and B are independently selected from the group consisting of hydrogen and the ##STR2## radical, X is a halogen having an atomic number from 17 to 53 inclusive and a, b and c are integers the sum of which equals a number from 0 to 3. These water-soluble glycidyl ethers of glycerine are prepared by reacting glycerine with an epoxyalkyl halide in the presence of a Lewis Acid catalyst, subsequently at least partially dehydrohalogenating the resulting product, and finally recovering the water-soluble glycidyl ether product. Both the condensation reaction and the dehydrohalogenation reaction are carried out in the presence of an organic solvent. The products of this invention are polymerizable and useful in the same way as other glycidyl ethers but additionally may be used in aqueous formulations for coatings, adhesives and the like.
