It was confirmed that the main chain of the polymer was oriented in the direction in which the electric field was applied, since light sometimes passed through! In other words, since the extinction position is exhibited where the electric field application direction matches the polarizer and analyzer directions, it can be seen that the polymer main chain is strongly oriented in the electric field application direction.
