摘要：
In this investigation, a series of novel poly(methyl methacrylate-co-N-2-methyl-4-nitrophenylmaleimide) (PMMA-co-MI) copolymers possessing high glass transition temperatures (Tg) and high transparency was prepared through free radical polymerization. The resultant copolymers were characterized by spectroscopic techniques, elemental analysis, X-ray diffraction, and thermal methods. The PMMA-co-MI copolymers demonstrate higher thermal stability as compared to pristine PMMA. The Tg of copolymers is about 40 °C more than for PMMA. The copolymer composition has been determined by elemental analysis and 1H-NMR. The investigated copolymers show excellent solubility in wide range of organic solvents.
