EPOXYDE COMPOSITION AND METHOD FOR PRODUCTION THE SAME Russian patent published in 2005 - IPC

FIELD: chemistry, in particular organic polymeric compounds and compositions.

SUBSTANCE: claimed composition contains epoxy-dianic resin with molecular weight at most 390, aliphatic epoxy resin, and triethyleneamin as curing agent. Composition is obtained by addition of 5-10 mass pts of aliphatic epoxy resin to 100 mass pts of epoxy-dianic resin and mixture is blended to obtain homogeneous mass. Then 13-14 mass pts of triethyleneamin as reduced to 100 mass pts of resin is admixed and cured at room temperature for one day followed by auxiliary curing at 100-120°C for 3-5 h. Composition of present invention is useful in production of heat resistant polymeric constructional materials for aerospace and machine industry.

EFFECT: epoxy compositions with improved strength and heat resistance.
