実験手順

19.22 g (0.098 mol) of CBDA, 9.77 g (0.08 mol) of 4-ABA and 5.85 g (0.02 mol) of DADOB were reacted in 197 g of NMP at room temperature for 5 hours to prepare a polyamic acid solution. The polymerization reaction proceeded easily and uniformly, and the molecular weights were measured in the same manner as in Preparation Example 1 and as a result, a solution of a polyamic acid having a number average molecular weight of 13,557 and a weight average molecular weight of 26,993 was obtained.
