Abstract
AbstractResults of investigations on the synthesis and characterization of free‐radical copolymerization of [(4‐isopropylphenyl) oxycarbonyl] methyl methacrylate (IPPOMMA), monomer (M2) with acrylonitrile (AN), and methyl methacrylate (MMA), monomers (M1) in CHCI3 solution at 60°C with AIBN as initiator are presented. Fourier transform infrared, 1H‐NMR, and elemental analyses techniques were used to identify of polymers. Reactivity ratios were calculated according to the general copolymerization equation using Kelen–Tüdös and Fineman–Ross linearization methods, yielding rAN = 0.60 plusmn; 0.14 and rIPPOMMA = 0.94 ± 0.28 for the AN/IPPOMMA system; rMMA = 0.76 plusmn; 0.30 and rIPPOMMA = 1.08 plusmn; 0.52 for the MMA/IPPOMMA system. The thermal properties of the polymers were studied by thermogravimetric analysis and differential scanning calorimetry. In addition, solubility parameters, inherent viscosities, and densities of polymers were determined. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 88: 2331–2338, 2003
