- Abstract
The cardanol‐based phthalonitrile (PN) monomer was successfully produced via the nucleophilic substitution reaction of cardanol with 4‐nitrophthalonitrile in potassium carbonate media. The conventional methods were employed to predict the chemical structure. The influence of long alkyl chains of cardanol was observed on the thermomechanical properties, recorded values were much below than the poly(Baph) standards. However, the thermal stabilities were recorded in good agreement to PN resin values. Furthermore, the 100 kGy dose of Co60 irradiation does not show any remarkable changes in the studied properties. The copolymers from P‐a benzoxazine and cardanol‐based PN (CPN) on the different wt % blending were prepared. The curing behavior and mechanism of the monomer blends were analyzed. The curing of CPN was improved in the presence of active hydrogen produced from the P‐a polymerization. The Tg and thermal properties of the copolymer were much better than the neat poly(P‐a). © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47505.
