The interaction between diglycidyl ether bisphenol A and 
conventional and water-deficient phosphate binders has been investigated. 
The data of chemical analysis, IR spectroscopy, and differential-thermal 
analysis point to the formation of a spatially cross-linked epoxy 
polymer under the influence of the phosphate binders. It has been 
shown that conventional binders can be used as high-temperature hardeners 
of epoxy oligomers. When water-deficient binders are used, the formation 
of a three-dimensional polymer structure is observed at room temperature.
