Several basic physical properties of poly(arylene ether ketone) s containing N-alkylcarbazole(PPCz E,PPCz B and PPCz H) were studied in comparison with the corresponding analog,commercialized phenolphthalein poly(ether ketone)(PEK-C). Strong UV absorption and blue light emission ability are exhibited by these polymers due to the introduction of carbazole structure. The water contact angle of polymers(87°~103°) is greater than that of PEK-C(76°),because of the hydrophobic nature of alkyl groups. While at the same time,these polymers have higher water uptake capabilities than PEK-C which is probably due to their larger chain distance. In addition,these polymers exhibit good dimensional stability(linear thermal expansion coefficient 6.4×10^-5℃^-1) and electrical insulating(volume resistivity 10sup>16Ω·cm) property. Young's modulus,tensile strength and elongation at break of these polymers are in the range of 1.9~2.0 GPa,72.5~75.0 MP and 6.5%~7.2%,respectively. Dynamic mechanical analysis shows that PPCz E remains good tensile property at the temperature up to 225℃.
