LC Copolymers Containing Both Nematogenic or Smectogenic and Active Side Groups

2 LC Copolymers Containing Both Nematogenic (or Smectogenic) and Active Side Groups 

IV Behavior and Properties of Side Group Thermotropic Liquid Crystal Polymers 

Factors (1), (2), and (3) clearly affect product reproducibility, which is vital if the properties of these polymers are to be correlated with structure and if they are to play a role in applications. 

A number of copolymers having nemat-ogenic (or smectogenic) and NLO active groups have been synthesized [155, 173-181]. Table 15 lists a number of chemical groups that have been used for their mesogenic properties. As can be seen from their formulas, highly polar terminal substituents 

The ability to gain molecular control of the LC character through synthesis is clearly outlined in Table 16 for copolyacrylates having the structure 25 [173].
