Summary

The efficiency of several solvent-nonsolvent systems in the process of fractionation of the Polish-made Epidian-1 resin with Mn = 1040 has been compared. The fractions thus obtained have been characterized by means of the GPC-method. The efficient fractionating systems were chloroform/heptane and toluene/isopropanol pairs, whereas the dioxane/water pair was much less effective. The problem of the relationship between the effectiveness of the fractionat­ing systems and the values of the solubility parameters of both thier components and the epoxide resin has been dis­cussed.
