CURING OF DIGLYCIDAL ESTERS OF BISPHENOLS WITH ACID HARDENERS

The unique properties of epoxy polymers have led to their wide application in various fields modern technology. influence the structure bisphenols on polymers, especially thermal ones, is known. However, chemical hardener also affects cured polymers. As hardeners, we used acid hardeners structures: anhydrides maleic, phthalic, pyromellite, methyltetrahydrophthalic and other acids. following give high results heat resistance: pyromellite anhydrides. Polymers obtained by curing with these are deformed temperature range 220-245°C. use gives terms stability. These formed components. It known that depend glycide ether. There was some interest investigating as a structure, well nature hardeners. For this purpose, diglycidal esters based were synthesized.
