Abstract: N-acryloylcarbazole was prepared in a two-step synthesis starting from carbazole, Poly(N-acryloylcarbazole) was prepared by bulk polymerization using benzoyl peroxide (BPO) as free-radical initiator at 100°C. N-acryoylcarbazole was characterized by One-dimensional NMR (1H,13C {1H} and Distortionless Enhancement by Polarization Transfer (DEPT))experiments. Assignments of One-dimensional NMR spectra were further confirmed by Two-dimensional Heteronuclear Single Quantum Coherence (HSQC) experiment and Total Correlation Spectroscopy (TOCSY). Characterization of poly( -acryloylcarbazole) was done by 13C {1H} and DEPT NMR experiments. The signals obtained for poly(N-acryloylcarbazole) were broad due to the restricted rotation of bulky carbazole group and the quadrupolar effect of nitrogen present in carbazole moiety. Assignments of One-dimensional NMR spectra were further confirmed by HSQC experiments. The molecular weight of poly(N-acryloylcarbazole) was determined by Gel Permeation Chromatography (GPC). Its thermal stability was determined by thermogravimetric analysis (TG/DTA) and Glass transition temperature (Tg) was determined by Differential Scanning Calorimetry (DSC).
