M. Kozlovsky et E. Demikhov, A TGB-LIKE, POORELY BIREFRINGENT SMECTIC PHASE OF SIDE-CHAIN POLYMERS, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 282, 1996, pp. 11-16
An almost optically isotropic smectic phase has been observed for some
side chain polymers having main chains of different nature (homo- and
copolymethacrylates, polysiloxanes) but the same chiral mesogenic sid
e group. Structure and optical properties of the mesophase are investi
gated.
