摘要: Abstract Polymers based on N-phenyl maleimide, N-4-propargyl methoxy phenyl maleimide and methyl methacrylate was synthesized. High glass temperatures 183, 179, 159 °C respectively for P 1 , 2 3 were achieved. EO polymer –C with about 30 wt% chromophore loading density prepared by attaching Chromophore C to using copper-catalyzed Huisgen cycloaddition reactions in mild reaction conditions high yield. Among the polymers, showed us best solubility normal solvents suitable temperature. films large coefficient of 50 pm/V @1310 nm good long-term stability, 85% activity kept after annealing at 85 °C 200 h.
