| 英文摘要 | A series of liquid crystalline (lc) epoxy monomers with different length of lateral substituents were cured with anhydrides. the cure kinetics was investigated by dsc technique. from a multi-temperature scan method, the activation energy e, and the frequency factor a were determined and compared for epoxides with different length of lateral substituents. the results showed that as the length of lateral substituent increases, the activation energy e. decreases, but the curing reaction of liquid crystalline epoxides become less active and is controlled by diffusion at the late stage of curing. the phase structures and the mechanical properties of the resulted lc epoxy resins were studied by pom, waxd, dma, tensile tests and sem. a nematic structure is observed. and as the length of lateral substituent increases, the cross-linking densities and glass transition temperature (t-g) of the lc networks decreases. the tensile modulus, together with break strength and elongation at break also decreases as the side chain increasing. |
