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