Journal Title: IOSR Journal of Applied Chemistry (IOSR-JAC) - Year 2018, Vol 11, Issue 4
Abstract
N-(9-ethyl carbazolyl) benzoxazine was synthesized by the reaction of 3-amino-9-ethyl Carbazole with paraformaldehyde and 4- methyl phenol under reflux in the solvent medium of toluene. The corresponding polybenzoxazine of N-Carbazolylbenzoxazine monomer was synthesized by heat treatment process. The following temperature program was applied:1100 c for60 min ., 1400 c for 30min., 1600 c for 30 min .,1700 c for 45 min, 1800 c for 45 min ., 1900 c for 60 min, 200 0 c for 90 min . The benzoxazine monomer and poly benzoxazine were characterized by IR, UV and NMR spectroscopy . Secondly a polymeric benzoxazine precursor was synthesized by the reaction of 3,6-diamino-N-ethyl Carbazole (which was Synthesized earlier) with paraformaldehyde and Bisphenol-A-under reflux condition in the solvent medium of chloroform. The polymeric benzoxazine precursor was characterized by IR,UV and NMR spectroscopy.
