成果简介	NOVELTY - Nadimide substituted bifunctional phthalonitrile resins (I) is new. USE - Nadimide substituted bifunctional phthalonitrile resins used for flame retardant composites and has ideal flammability specifications effective for submarine applications. ADVANTAGE - The nadimide substituted bifunctional phthalonitrile resins promises candidates for the development of high performance cross-linked thermoset polymers with unique properties of low dielectric constants, radar transparency, flame retardance, and superior adhesive properties for utilization in high temperature resistance applications, has industrially cost effective synthetic route is utilized for the synthesis of the nadimide substituted phthalonitrile resins and development of the resins to the corresponding cross-linked thermosetting polymers, high temperature thermo oxidative stability, good adhesive properties and excellent mechanical strength. DETAILED DESCRIPTION - Nadimide substituted bifunctional phthalonitrile resins of formula (I) is new. Ar'=phenyl derivative of formulae (II-IV); and n=0 or 1. An INDEPENDENT CLAIM is included for a method for preparing nadimide substituted bifunctional phthalonitrile resins of formula (I).
