Currently, ABS is produced by two different technologies: emulsion and continuous mass. Both technologies can produce materials with peculiar properties, but not always overlapping. The emulsion technology is more suited to produce high-performance m

It is shown that the addition of 2 to 6 wt.% of a chiral dopant (CD) to a series of nematic copolymers (Pn) induces blue and cholesteric mesophases. The mesomorphic behaviour of various CD+Pn mixtures is investigated by polarized optical microscopy a

The dynamics of a chiral polymorphic liquid crystal smectogen (8BEF5), partially deuterated on the aromatic core and on the chiral chain, has been investigated in its smectic A and C ∗ phases. The 2 H T 1Q and T 1Z spin–lattice relaxation times,

The structure, magnetic alignment and orientational order of polysiloxane liquid crystal copolymers were investigated by X-ray diffraction and 2 H NMR spectroscopy. The copolymers incorporated significant amounts of non-mesogenic counits, and the inf
