THERMOSETTING RESIN SYSTEMS CONTAINING SECONDARY AMINE-TERMINATED SILOXANE MODIFIERS Modified heat-curable resins having enhanced toughness are prepared through incorporation of certain secondary amine terminated organosilicones or prereacts of these organosilicones with epoxy, cyanate, or bismaleimide resins. These modified resins are useful as toughened matrix resins, as high temperature, high strength elastomers, and, particularly, as structural adhesives. |
