A new bisphenol monomer with pyridyl groups (compound 3) was synthesized via a two-step reaction. A series of functional poly(aryl ether ketone)s with pyridyl groups on the side chains (Py-PAEKs) were prepared by a nucleophilic substitution polycondensation of new bisphenol monomer, 2, 2-di(4-hydroxy phenyl)propane and easily available bisfluoro monomer at various molar ratios. Structures of compound 3 and Py-PAEKs were determined by means of 1 H-NMR, IR spectra and elemental analysis. Thermal analysis of Py-PAEKs revealed that the glass transition temperature (T g ) and the 5% weight loss temperature (T 5% ) of these copolymers varied in the range of 147-176 C and 432-330 C, respectively, which showed strong chain rigidity and excellent thermal stability. Moreover, Py-PAEKs were soluble in some organic solvents under heating, which made them potentially used for self-assembly of rigid polymers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
