Abstract
Resin compositions comprising inorganic species selected from the group consisting of siloxanes and phosphazenes in combination with and capable to being bonded to thermoset and/or thermoplastic resin system derivable from cyanate functional monomers and/or oligomers. Reacted resin compositions are found to have enriched areas of the inorganic species. The resin compositions have a variety of improved properties including toughness and improved resistance to oxidation.
