Copolymers of 2,4,6‐tribromophenyl acrylate (TBPA) (1) and glycidyl methacrylate (GMA) (2) with different feed ratios are synthesized in toluene using benzoyl peroxide as a freeradical initiator at 70 ± 1°C. The copolymer composition is calculated using 1H‐NMR spectroscopy by comparing the intensity of aromatic and aliphatic protons. The copolymers are characterized with FT‐IR and proton decoupled 13C‐NMR spectroscopic techniques. The reactivity ratios are calculated by Kelen‐Tüdos method and are r1 = 1.08 ± 0.53, r2 = 0.52 ± 0.26. Gel permeation chromatography is used for determining the M̄n, M̄w molecular weights and dispersity index. Thermogravimetric analysis is employed for the determination of thermal stability of homo‐ and copolymers. The glass transition temperatures of the poly(TBPA), poly(GMA), and copoly(TBPA‐GMA) are determined by differential scanning calorimetry.
