A monomer of 5-indanyl Methacrylate (5-IMA), has been synthesized from the precursor viz., 5-indanol and characterized by Fourier transform infrared (FT-IR), Nuclear Magnetic Resonance Spectroscopic Techniques 1HNMR and13C-NMR.Copolymerization of 5-IMA with Methylmethacrylate (MMA) is carried out in benzene by free radical Solution polymerization at 70°C using Benzoyl Peroxide as initiator. 5-IMA–co-MMA Copolymers are characterized by Fourier transform infrared (FT-IR), Nuclear Magnetic Resonance Spectroscopic Techniques (1HNMR) spectroscopy. Analysis of the thermal properties of the Copolymer by Thermogravimetric analysis (TGA)and Differential Scanning Calorimetry Analysis(DSC) are also reported
