초록

Poly(amic acid) precursors were prepared by mixing various main chain dianhydrides, main chain diamines and side chain diamines. The side chain diamine has an alkylbicyclohexyl group as a side chain. The copolyimide films, produced by casting the poly (amic acids) solution, exhibited the vertical alignment property without the rubbing process in the range of the curing themperature from $90^{\circ}C$ to $240^{\circ}C$ for 1h. The thermal and surface properties of the poly(amic acids) depending on the curing temperature was examined.
