الإجراء التجريبي
19.22 g (0.098 mol) of CBDA and 12.22 g (0.1 mol) of 3-ABA were reacted in 283 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 28,114 and a weight average molecular weight of 45,429 was obtained. Further, to this solution, poor solvents BCS and NMP were added so that the polyamic acid concentration would be 5 mass % and the BCS concentration would be 20 mass % to prepare a liquid crystal aligning agent.
