摘要：

We present the results of our studies of the ferroelectric properties of mixtures of a high polarization, ferroelectric liquid crystalline copolymer and its side-group antecedent, a high polarization, low molecular weight, ferroelectric mesogen. These two materials are found to be completely miscible in all proportions. Spontaneous polarization values and electro-optical response times are found to be monotonic functions of the weight percentage of the mesogen in the mixture, while optical tilt angles do not exhibit such a monotonic dependence.
