Abstract

Results of investigations on the synthesis and characterization of free-radical copolymerization of [(4-isopropylphenyl) oxycarbonyl] methyl methacrylate (IP-POMMA), 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.
