SYNTHESIS AND CHARACTERIZATION OF COMB-LIKE POLYMERS BEARING HETEROCYCLIC AZO GROUP AND MESOGENIC GROUP

Received Date: 20 September 1997

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 monomer MAPB2 nad the glass transtion temperatures of the polymers increase with increasing content of azo moiety in polymers linearly.
