Title Novel Phosphorous-Containing Aromatic Polyethers - Synthesis and Characterization
Date 16.02.2005
Number 12610
Abstract <B>Summary:</B> 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 <I>T</I><SUB>g</SUB>s, high thermal stabilities as well as modified flame retardance properties depending on the diol type incorporated.
