Summary
Two kinds of chiral side chain liquid crystalline polyacrylates were synthesized and characterized by DSC, POM and x-ray diffraction. The results indicated that chirality of side chain end group and spacer length strongly influence the phase behaviour of the polymers. The polymer P-I with one asymmetric carbon atom of end group exhibits enantitropic Smectic SA and SC phases. The polymer P-III having two asymmetric carbon atoms displays enantitropic Smectic SA and SB phases. Formation of liquid crystalline polymorphism of polymers depends on spacer length of side chains.
