Abstract

High-performance polymer materials have excellent performance at high temperatures and are indispensable in aerospace, electronics, electrical engineering, high-speed rail, and other important high-tech fields. Improving the processing performance of polymers without sacrificing their heat-resistant property is a research hot spot. Phthalazinone-containing high-performance polymers are a new class of high-performance polymer materials. This article reviews progresses in the synthesis and performance of phthalazinone-containing poly(aryl ether)s (including poly(phthalazinone ether sulfone ketone)s, poly(phthalazinone ether nitrile sulfone ketone)s, poly(phthalazinone ether sulfone ketone ketone)s, and poly(triaryl triazine ring)s), polyamides, polyimides, polyarylates, and polybenzimidazoles. Because the phenyl-phthalazinone structure is a twisted, non-coplanar, and fused ring, the above polymers are not only heat resistant but also soluble. The processing methods are diverse and include both ...
