반응 단계
270 mg of 5%-Pd/C was suspended in 14 mL of a 1:1 mixed solvent of ethanol and benzene. While passing hydrogen through the system, a solution was added that consisted of 3.21 g of the 4,4'-dinitrobiphenyl-containing polysiloxane (average value of n: 14.4) synthesized in Reference Example 2 dissolved in 14 mL of the same mixed solvent. Hydrogen was injected into the system for 3 hours while stirring. The catalyst was then filtered off and the solvent was distilled under reduced pressure to give 3.00 g of the 4,4'-diaminobiphenyl-terminated polysiloxane as a viscous yellow liquid.
