Several novel mesogenic spiro-orthoester monomers such as 1,6,10trioxaspiro [4,5]decanes 4, containing biphenyl mesogens at the C-8 positions of the fiveand six-membered spirocyclic ring, through the alkylene spacers of different lengths were prepared by condensation reaction of the corresponding bi
## Abstract The synthesis and thermal properties of a new type of sideβchain liquidβcrystalline polysalts are described. The polymers are first obtained by partial or complete alkylation of a linear poly(ethyleneimine) with 6β(4βmethoxyβ4β²βbiphenylyloxy)hexyl bromide or 12β(4βmethoxyβ4β²βbiphenylylo
