Modification of Epoxy Resin by Reactive Block Copolymer SEBSMB

Abstract:

Reactive block copolymer SEBSMB was used as modifier to toughen epoxy resin. The results indicate that ideal enhancement of toughness could be achieved by this method. The impact strength increases with increase of the content of SEBSMB in the matrix and it could be enhanced by 200% at 20wt% addition of the modifier. DMA and TG results show that the modified resin exhibits similar thermal stability as compared with pure epoxy resin. The toughening effect may be ascribed to the unique self-assembling structure of SEBSMB in the matrix and a hypothetical model was proposed.
