Step-growth polymers and networks were prepared with the nucleophilic aromatic substitution of perfluoropyridine with phenolic substrates. Linear AA-BB type, step-growth polymers were prepared to afford transparent, flexible films that exhibit excellent solution process ability in common organic solvents. Networks of similar type were optimized to produce highly densified crosslinks with moderate thermal stability and exceptional char yields. Herein, we highlight a new methodol. and their thermal properties for the preparation of linear and network polymers without the need to pre-install labile moieties producing materials of interest for high performance materials and potential applications thereof. This study involved multiple reactions and reactants, such as 2,3,4,5,6-Perfluoropyridine (cas: 700-16-3Recommanded Product: 700-16-3).
2,3,4,5,6-Perfluoropyridine (cas: 700-16-3) belongs to pyridine derivatives. Pyridine is diamagnetic and has a diamagnetic susceptibility of 鈭?8.7 脳 10鈭? cm3路mol鈭?.The molecular electric dipole moment is 2.2 debyes. The standard enthalpy of formation is 100.2 kJ路mol鈭? in the liquid phase and 140.4 kJ路mol鈭? in the gas phase. One of the examples of pyridines is the well-known alkaloid lithoprimidine, which is an A3 adenosine receptor antagonist and N,N-dimethylaminopyridine (DMAP) analog, commonly used in organic synthesis.Recommanded Product: 700-16-3
