Ternary copolymerisation of glycidylmethacrylate (GMA), with different alkyl acrylates (methylacrylate (MA), methylmethacrylate (MMA), butylacrylate (BuA) and n ‐butylmethacrylate ( n ‐BuMA)) and acrylonitrile (AN)) were carried out in solution at 65°C in the presence of a free radical initiator. Experimental terpolymerisation data agree well with calculations based on the Alfrey‐Goldfinger equation. The determination of unitary, binary and ternary azeotropes of the various systems studied was easily handled by a computer. Ternary azeotropic compositions for GMA‐MMA‐AN and GMA‐ n BuMA‐AN systems were found to be 17‐50:68‐50:14‐00 and 51‐00:3‐00:46‐00 mol%, respectively. Also, 'pseudo‐azeotropic' regions were identified where the deviation between feed and polymer compositions was very small.
