abstract = {The mesostructure of segmented poly(urethane imide)
containing 4–10 wt $\%$ CoFe2O4 orAl3Fe5O12 nanoparticles
was experimentally studied by small-angle polarized neutron
scattering, which cananalyze the nuclear and magnetic
subsystems of the obtained composites. The transformation of
the domainstructure of the magnetic elastomers based on
poly(urethane imide) was investigated at various
concentra-tions, chemical compositions, and localizations of
ferrite nanoparticles in polymer chains. The dynamics ofthe
change in the segmental mobility of soft blocks during
heating of samples was characterized by magnetic–nuclear
interference scattering. The experiments detected changes in
the supramolecular structure of themultiblock copolymer,
which depended on the percentage and type of nanoparticles.
The correlation radiiwere determined in the magnetic
subsystem of ferrite nanoparticles embedded in hard aromatic
blocks ofpoly(urethane imide) as nodes of intermolecular
crosslinkers and chain extenders. The temperature
depen-dence was analyzed for the intensity of small-angle
nuclear scattering by poly(urethane imide) and
magneticelastomers based on it, under the conditions of the
transition of soft aliphatic segments from the glassy to
thehighly elastic state.},
