Phthalonitrile-functional multiple arylene ether nitrile-containing phthalazinone moiety: facile synthesis, curing, and properties

Abstract: This article discloses a series of processable multiple phthalazinone-based ether nitriles with various contents of phthalonitrile ends (compounds 4a–4e) and compares the cyclization feasibility of terminal phthalonitrile and pendant cyano group. Compounds 4a–4e were synthesized by facile polycondensation of excess 4-(4-hydroxyphenyl)-2,3-phthalazine-1-one (compound 1) with 2,6-difluorobenzonitrile (compound 2), followed by end-capping of 4-nitrophthalonitrile (compound 4). Their number-averaged molecular weig… Show more

“…To compensate for the negative effects, a class of phthalonitrile terminated polyaryl ether nitrile has been attracting more attention recently. A series of novel phthalonitrile terminated polyaryl ether nitrile were reported . The lateral cyanide structure was considered as potential cross‐linkable groups to improve the thermal and mechanical performance of the resin.…”

“…[6][7][8][9][10] However, these resins also exhibit some distinct limitations in that they are extremely difficult to polymerize, requiring several days at elevated temperature before gelation occurs. Despite a high temperature of approximately 350 C and a long time of approximately 20 h, it is still hard to observe polymerization.…”

“…This thermosetting resin was synthesized via the thermal curing reaction of phthalonitrile‐terminated oligomers. Usually, there are two common curing agents for the curing reaction: one is Lewis acid such as ZnCl 2 , and the other is aromatic diamine such as 1,3‐bis(3‐aminophenoxy)benzene ( m ‐APB), bis[4(4‐aminophenoxy)phenyl] sulfone ( p ‐BAPS), and bis(4‐aminophenyl)‐sulfone (BAS) . However, relatively high curing temperature and long curing time are the major problems concerned in the current status of research and application.…”
