Nematogenic side chain polymers

The applicability of the rule of selective miscibility has been also examined for mixturg gf nematic side chain polymers with conventional nematogens In contrast to linear polymers, onli-...

In the side chain liquid crystalline polymers the nematogenic side groups and chiral side groups are attached respectively to a polymer backbone to form a copolymer. They exhibit the cholesteric phase. A typical example is shown below. One is the homopolymer (shown in Figure 6.28) and the other is the copolymer (Figure 6.29).
