中文摘要	crosslinkable side-chain liquid crystalline polyesters pcn from n-[n-(4-(4-nitrophenylazo)phenyloxy)alkyl]diethanolamine (cn, n = 3, 5, 6, 10) as mesogenic monomers and maleic anhydride were synthesized and characterized. the thermal properties of pcn's were studied by means of dsc, polarized optical microscopy (pom) and wide angle x-ray diffraction (waxd), and the results showed that all the polymers studied exhibit enantiotropic liquid crystallinity. in the molar mass independent region, the relatively high content of cis -ch=ch- groups in the polymer backbone of pc3 causes an increase of the melting temperature (t-m) and a decrease of t-g and isotropisation temperature (t-i). the crosslinking of pcn in the radical polymerization with styrene was confirmed by ftir spectroscopy. the absorption band at 1300 cm(-1) attributed to the in-plane c-h-bending vibration of trans -ch=ch- in the polymer backbone disappeared after crosslinking, indicating that the trans -ch=ch- functions are consumed in the crosslinking polymerization of styrene.
