摘要：<p>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. <IMAGE></p>
