Design and properties of polyarylene ether nitrile copolymers with improved elongation at break
Polyarylene ether nitrile (PEN) based on biphenol exhibits a high glass transition temperature of 216 degrees C, a high tensile strength of 110 MPa, and low elongation at break of approximately 4%. A series of PEN random copolymers with improved elongation at break were synthesized using various bisphenol compounds and 2,6-dichlorobenzonitrile (DCBN). The resulting PEN random copolymers exhibited a high glass transition temperature and thermal stability up to 513 degrees C in a nitrogen atmosphere. PEN copolymers were amorphous and could easily be cast into transparent films with a tensile strength of 97.93-117.88 MPa and tensile modulus of 2187.98-2558.44 MPa. Most importantly, elongation at break of these PEN copolymers was higher than 13%. PEN copolymer films had a dielectric constant of 3.77-3.89 at 1 kHz and extremely low dielectric loss (<0.02). At the same time, the breakdown strength of PEN was in the range of 137.92-198.19 kV/mm and energy storage density was in the range of 0.32-0.68 J/cm(3). Excellent mechanical, thermal, and dielectric properties of PEN make it possible to use them as high-temperature resistant dielectrics to act on high-temperature resistant insulated cables. But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 163931-61-1, you can contact me at any time and look forward to more communication.
