| Abstract: | Two series of title polymers were prepared.By using IR,polarized light mi-croscope and DTA,their structure and properties were identified.Their melt index were alsobe determined. The results showed that all polymers prepared were thermotropic liquid cryrt-ailine polymers and formed nematic phase only. |
