Synthesis and Properties of Styrene/Maleimide Copolymer with Active Side-group

Styrene/N-(4-hydroxyphenyl) maleimide copolymer(SHMI), which has an active side-group and can be reacted with other organic molecules with special optical and electrical properties, were synthesized. SHMI can be used as backbone for functional and special polymers. The structures of SHMI products were studied by FTIR, NMR and GPC. DSC and TGA were employed to study the thermal transition and thermal degradation of SHMI. It is shown that SHMI is an alternating copolymer with high glass transition temperature(T-g =526 K), good solubility and film-forming properties. The thermal degradation kinetics of SHMI can be fitted by Arrhenius equation. The initial thermal degradation temperature(T-{d1}) of SHMI is 661 K.
