Summary

A series of polymethacrylates containing brominated carbazolyl pendant groups was obtained by using microwave irradiation in the synthesis of monomers. The modified methacrylates were polymerized in toluene as solvent with AIBN as initiator. TGA showed the bromo-derivatives to have higher initial decomposition temperatures (IDT) as compared with the IDT of the original polymer containing no bromine. Thermal stability of the bromo-derivatives was found to be related to the number of bromine atoms introduced into the carbazole ring and to rise in the ascending order: 3-Br < 3,6-di-Br < 1,3,6-tri-Br. The 1,3,6-tri-Br derivative was found to exhibit the maximum IDT temperature difference, viz., 40°C.
