N ‐Aryl methacrylatoethyl carbamate monomers were prepared by reacting phenyl isocyanate/4‐chlorophenyl‐isocyanate and 2‐hydroxyethyl methacrylat, Homopolymerisation and copolymerisation with methyl methacrylate in a tetrahydrofuran solution was carried out using azobisisobutyronitrile/benzoyl peroxide as an initiator at 60°C. Molecular characterisation of polymers was done by intrinsic viscosity determination at 30°C in chloroform and molecular weight determination by gas permeation chromatography using poly(methyl methacrylate) standards. Molecular weight distribution ranged from 1.5 to 2.63. Copolymer composition was determined by using 1 H‐NMR. Thermal behaviour of the polymers in a nitrogen atmosphere was evaluated using dynamic thermo‐gravimetry.
