Abstract: A composition having enhanced fracture resistance comprising curable dicyanate ester resins having incorporated therein at least one thermoplastic polymer modifier which is soluble in the dicyanate ester resin. Said thermoplastic polymer undergoes an in-situ phase separation process during cure to form a microphase-separated multiphase thermoset material.

Abstract: Derivatives of compounds containing a carbonyl group conjugated to an aromatic moiety and methods of fabrication thereof consisting of a thioether, an ester, an ether, a phosphate and a silylether. Electrons are supplied to the carbonyl group conjugated to an aromatic moiety to form a reduced material. The reduced material is contacted with an electrophile which attacks and chemically combines with the carbonyl group conjugated to an aromatic moiety. The parent material can be regenerated by hydrolysis of the derivative. A silyl derivative can be selectively formed on a polyimide material surface which can act as a barrier to an RIE etch of the polyimide material. After etch the polyimide material is regenerated from the silyl derivative.
