Studies on the fractionation of epoxideresins. Part II Molecular distillation of Epidian-6 resin and characterization of fractions


Polimery 1984, No 3, 102


DOI: dx.doi.org/10.14314/polimery.1984.102

Summary

The Epidian-8 epoxy resin has been divided Into two fractions — distillate and residue — by molecular distillation. Both fractions have been analysed by the GPC method. The distillation residue has been fractionated next In the toluene/n-hexane system and the thus-obtained secondary fractions also characterized by the GPC method. The molecular distillation is more selective but less universal method of fractionation of epoxide resins than that of fractional precipitation in solvent/non-solvent systems
