The solubilities of bis(4-methylphenyl)phosphine sulfide (BMPPS) and bis(4-carboxyphenyl)phenylphosphine oxide (BCPPO) in acetic acid were measured. The concentration of the solution was determined by sodium hydroxide with phenolphthalein as indicator. The solubilities of BMPPS were measured over the range of 64−104 °C, and the solubilities of BCPPO were measured over the range of 66−106 °C with uncertainties of 3% and 2%, respectively.
A series of new poly(phosphine oxide ether ketone)s has been prepared from bis[4-(4-fluorobenzoyl)phenyl]phenylphosphine oxide and various bisphenols by the aromatic nucleophilic substitution reaction in DMAc. Monomer 1 was readily prepared by Friedel–Crafts acylation from bis(4-chloroformylphenyl)phenylphosphineoxide.
