| Résumé : |
Hyperbranched polamine has been prepared by an A2 + B3 approach using cyanuric chloride and diamine. This hyperbranched polyamine has been used to cure commercially available bisphenol-A base epoxy and a vegetable oil based epoxy resin at different dose levels (10-30 phr) with and without commercial poly(amido amine) hardener. The drying time, hardness, impact and chemical resistance of the cured epoxy resins have been investigated. The studies on morphology, thermostability and flame retardancy of cured films indicate the unifor distribution of different phases, high thermostability (up to 250°C) and seld extinguishing characteristics respectively. Results show that these hyperbranched polyamines could be used for epoxy resins as a potential agent for curing. The performance characteristics as coating materials are also improved by this active agent. All resutls obtained from this studied are be presented in this paper. |
