Abstract:
A blend of epoxy resins includes a) an epoxy resin composition derived from the reaction of a liquid epoxy resin, a carboxyl terminated butadiene (CTB), and a carboxyl terminated polybutadiene-acrylonitrile (CTBN) and/or a random and terminal carboxyl functional polybutadiene-acrylonitrile (CTBNX), and b) unreacted epoxy resin. The carboxyl terminated butadiene is miscible with the unreacted epoxy resin and does not separate therefrom even upon aging. Upon cure as with a latent cure agent, a toughened epoxy resin is produced having unexpected good low temperature properties such as peel strength.
