Hydantoin based epoxy resins

During recent years, various hydantoin based heterocyclic glycidyl amine resins have been developed. In these resins the presence of nitrogen containing heterocycle provides extensive variation in polarity, viscosity and hydrophobicity by the choice of alkyl groups. Most of these resins have low viscosity, high polarity and long pot life ensuring easy wetting and good adhesion. These resins can provide useful properties for casting, fibrous reinforcement, adhesives and coatings. In the present work, two resins, 1‐glycidyl‐ 3‐glycidyloxymethyl‐5, 5‐dimethylhydantoin and 1‐glycidyl‐3‐(2‐glycidyloxybutyl)‐5, 5‐dimethylhydantoin have been prepared using 5, 5‐dimethylhydantoin as the starting raw material. The resins have also been characterised for their various physical and chemical properties.
