"liquid crystals" . "New types of liquid-crystalline (LC) linear and crosslinked polyurethanes (LCPU) with LC side chains (with rod- or banana-shaped mesogens) and polybutadiene backbone sill be prepared. Such materials may have a huge potential for high-tech applications in photonics. Four major objectives will be: a) the synthesis of various classes of banana-shaped and rod-like LC compounds terminated with thiol groups with the aim to get new gerroelectric and entiferroelectric mesophases with dipolar order, agrafting these molecules onto pobutadiene-diols ofvarious lengths, b) the synthesis of linear and crosslinked LCPU from grafted polybutediene-diols, diisocyanates and triols of different rigidity, c) investigation of the influence of the chemical structure of reactants and LC state of diols together with synthesis conditions on the process of thenetwork formation, gelation and final structure of LCPU networks and d) extensive physical studies and evaluation of material properties of LCPU."@en . .
