| Abstract: | The orientational behavior of nematic LC copolymers (4-{[6-(acryloyloxy)hexanoyl]oxy}phenyl-4-propoxybenzoate)-co-(4-(6-acryloyloxypropyl-1-oxy)benzoic acid) in a magnetic field has been studied by 2H NMR spectroscopy. An increase in the content of carboxyl groups in the copolymer leads to an appreciable growth of the orientational order parameter S zz . |
