Summary

The synthesis of a new series of α-oxiranes containing 4-cyanobiphenyl andp-methoxyphenyl benzoate mesogenic groups and the phase behaviour of synthesized compounds are described. Polymerization of α-oxiranes with BF3.O(C2H5 2) and Et3Al/H2O/Acetyl acetone as initiators was carried out. The first initiator produced oligomers displaying liquid crystalline properties while the second gave crystalline polymers with a high degree of polymerization.
