Terpolymers of acrylonitrile (AN), vinyl acetate (VA) (7.5–30 mol‐%, related to AN), and divinylbenzene (DVB) (10 wt.‐%) were prepared by suspension polymerization. The diluents used were mixtures of toluene or cyclohexanol (90 vol.‐%) with solvents (10 vol.‐%) such as hexadecane (HD), octane (O), dodecane (D), 2‐ethylhexanol (E) or benzyl alcohol (B). It has been found that AN‐VA‐DVB terpolymers have a higher porosity, about 0.61–0.68, than corresponding AN‐DVB copolymers. The terpolymers obtained with mixtures of various diluents differ in their supermolecular structure although they had similar porosity characteristics. The thermal effects accompanying heating of the terpolymers above 200°C significantly exceed that of nitrile groups cyclization observed of the other AN polymers. © 1991 Hüthig & Wepf Verlag, Basel
