Novel phosphorous-containing aromatic polyethers : synthesis and characterization

The synthesis of novel phosphorous-containing aromatic polyethers P-PEEK and P-PSU, based on poly(ether ether ketone)s (PEEK) and poly(ether sulfone)s (PSU) was carried out successfully by using phosphorous-containing aromatic diols instead of bisphenol A in the usual synthesis procedure. The molecular weights of the P-PEEKs and P-PSUs obtained reflect both the influence of the different halogen components used and the lower thermal stabilities of the phosphorous-containing diols compared to bisphenol A. However, polymers with sufficient molecular weights could be obtained, having interestingly high T g s, high thermal stabilities as well as modified flame retardance properties depending on the diol type incorporated.
