Main results
- Investigated mechanism of transition of
flexible polymers from isotropic to oriented state by
using X-ray method, deformation calorimetry, infrared
spectroscopy, radiothermoluminescence
- Developed applications of fluctuation
statistical theory of phase transitions and critical
phenomena to explanation of dynamic and structural
properties of linear semicrystalline polymers
- Established the reason of yielding and
necking
- Developed unique techniques including a
combination of experimental X-ray analysis methods,
fluctuation theory of phase transitions, computer
modeling with reconstruction of electron density maps for
study of new thermotropic materials based on benzene sulfonic acid
and polymethacrylates (and their precursors) with volume side groups of different
chemical nature in comparison with lyotropic systems such
as the complexes of linear and network polyelectrolytes
with oppositely charged surfactants
