Abstract

In the present study Copolymer Poly(2,4 dinitro (phenyl amino) maleimide-CO-MMA ) [C-DNPAMI] was synthesized with 2,4 dinitro derivative of phenyl amino Maleimides[DNPAMI] and methyl methacrylate[MMA] using Azobisisobutyronitrile [ AIBN] as initiator in Tetrahydrofuran [THF] at 650 C. Nine copolymer samples were prepared from different feed ratios of comonomer. The monomer reactivity ratios were determined by Fineman Ross method. The structure of copolymer was confirmed by FT-IR and 1H NMR. The effect of reaction solvent and initiator has been investigated to find suitable conditions for preparation of copolymer with high percentage yield. The molecular weight of polymer sample was determined by GPC. The copolymer was characterized by elemental analysis, Solubility, density, viscosity and thermal analysis. The initial decomposition temperature of copolymer samples were in the range 250 to 550C.
