반응 단계
In accordance with the procedure of Preparation Example 1, a polyimide resin solution was obtained using 288 grams (0.98 mol) of 3,3,4,4-biphenyltetracarboxylic dianhydride as a tetracarboxylic dianhydride component, 74.6 grams (0.3 mol) of 1,3-bis(3-aminopropyl)-1,1,3,3-tetramethyldisiloxane and 287.4 grams (0.7 mol) of 2,2-bis[4-(4-aminophenoxy)-phenyl]propane as diamine components, 6 grams (0.04 mol) of phthalic anhydride as a molecular weight modifier, and 2,600 grams of NMP as a solvent. The solution was poured into 5 liters of methanol whereupon a precipitate settled out. Vacuum drying yielded 615 grams of the end polyimide resin.
