| 摘 要： | A series of newly designed monomers of 2-vinylterephthalates (VT) were synthesized. The monomers contain onephenylene group connected with two alkyl groups (carbon number varying from 1 to 6) via ester linkage. Their chemicalstructures were confirmed by mass spectroscopy (MS), ~1-H-NMR, and elemental analysis (EA). The corresponding polymers,polydi(alkyl) vinylterephthalate]s (PDAVTs), were obtained using convenional free redical polymerization. The polymerswere found to be able to develop inio liquid crystalline phase when the size of the alkyl group in the side-chain increases tobe larger than the ethyl group.
