| 摘 要： | The synthesis and characterization of a series of novel comb-like polymethacrylates bearingheterocyclic azo group and mesogenic group are described. The thermal properties of the polymers such asthermal stability and phase transition behavior were investigated by thermogravimetric analysis, differentialthermal analysis and polarizing optical microscopy techniques. The experimental results show that all thesynthesized polymers do not exhibit liquid crystallinity except the homopolymer of the mesogenic monomerMAPB2 and the glass transition temperatures of the polymers increase with increasing content of azo moietyin polymers linearly.
