Description
Poly(arylene ether)s containing imine units were prepared by the aromatic nucleophilic displacement reaction of potassium salt of bisphenols with bis(fluorophenyl) compound activated by imine in N-methyl-2-pyrrolidone at elevated temperature. Polymers having inherent viscosities of 0.3—0.6 dl g−1 were obtained after polymerization for 4—7 h. The polymers had glass transition temperatures from 141 to 198°C and decomposition temperatures (5% weight loss under air atmosphere) from 445 to 544°C depending on the bisphenols used. Isothermal TGA measurements (400°C under air or nitrogen atmosphere) revealed that the 4,4′-biphenol-based poly(arylene ether imine) belonged to the superior class of heat resistant polymers. The cast films of these polymers exhibited tensile strength, moduli, and elongations at 23°C of 70—100 MPa, 2.5—3.6 GPa, and 6—17%, respectively.
