Abstract
The copolymers (C-NACPMI) with various proportions of N-[4-N'-(4-nitrophenyl) aminocarbonyl] phenyl) maleimide [NACPMI] with Vinyl Pyridine [VP] and 2-hydroxy ethylmethacrylate (OHEMA) were prepared by free radical polymerization. The structure of synthesized copolymers was characterized by FT - IR and 1H-NMR spectroscopic methods. The nine copolymer samples were synthesized from different feed ratio of comonomers. The monomer reactivity ratio r NACPMI, r VP and r OHEMA are determined by Finemann Ross method. Copolymers showed solubility in polar solvent. Thermal behavior of copolymers was evaluated by TGA and DSC. The investigated copolymers degrade in one steps. The molecular weight was determined by GPC.
