摘要：

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-degrees-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-nBuMA-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.
