“…With this connection, we had set optimal temperature regimes for these reactions. It was expedient to do this, while also keeping in mind that compounds for electronic and radioengineering devices, as well as polymeric and sealing materials for various purposes, were designed on the basis of the given polymers [28][29][30]. Distinction in reactive capability of catalysts exerts appreciable influence on rheological properties of reaction mixes.…”

We report the curing process of epoxy oligomers by using isomethyltetrahydrophthalic anhydride catalyzed with 1-butyl-3-methylimidazolium salts. Catalytic action has been ascertained to be dependent on the nature of anion. Salts with(Br-)and(PO4-)anions appeared to be most active. Formation of salt adducts with epoxy resin and anhydride is shown. Polymers having higher values of strength and glass transition temperature—as compared with similar epoxy systems cured in the presence of tertiary amines as catalysts—are prepared.
