The synthesis of exo ‐ N ‐3,5‐bis(trifluoromethyl)phenyl‐7‐oxanorbornene‐5,6‐dicarboximide (TFMPhONDI, 2a ), exo ‐ N ‐4‐fluorophenyl‐7‐oxanorbornene‐5,6‐dicarboximide (FPhONDI, 2b ), and exo ‐ N ‐pentafluorophenyl‐7‐oxanorbornene‐5,6‐dicarboximide (PFPhONDI, 2c ) monomers is described. Poly(norbornene dicarboximide)s were obtained via ROMP using bis(tricyclohexylphosphine)benzylidine ruthenium(IV) dichloride ( I ) and tricyclohexylphosphine [1,3‐bis(2,4,6‐trimethylphenyl)‐4,5‐dihydroimidazolilydene][benzylidene] ruthenium dichloride ( II ). Poly‐TFMPhONDI ( 3a ) bearing a trifluoromethylaryl moiety showed a higher T g and improved mechanical properties as compared to poly‐FPhONDI ( 3b ) and poly‐PFPhONDI ( 3c ).
