The most important results

Studying the reactive formation process of the mixtures of linear polymers and semi-IPNs allowed establishment of the basic regularities of phase-separated structures emergence and determination of the factors having impact on the proceeding of this process, morphology and properties of resulting products. Both the fillers introduced to the reaction system in different ways and oligoazoinitiators of polymerization serving as mixture compatibilizers were shown to be effective modifiers.

The method of synthesis of titanium-containing IPNs with chemically bonded titanium having unique photochromic properties and photosensitivity was developed.

Gradient IPNs were obtained and the possibility to predict gradient profiles of different geometry was shown. Correlation functions of properties upon composition for transition from gradient concentration profiles to the profiles of viscoelastic and damping performance distribution within the layers of gradient IPNs.

By combining the principles of IPNs and technology of molecular imprinting nanostructured molecular-imprinted polymers were synthesized. On the basis colorimetric test-systems for detection of certain substances concentration in environmental conditions were elaborated.

New optically transparent coatings formed under irradiation of artificial UV-light or sunlight at environmental conditions can properly protect the surface of photovoltaic cells and enhance their energy efficiency.

Optically transparent polyurethane coatings with immobilized organic dyes as solid-state laser elements were developed. In these materials the generation characteristics of lasers and photostability of dyes are improved.

Polymer composites with hemp woody core as reinforcement capable of covalent bonding with epoxyurethane matrices based on castor and epoxydized soybean oil were obtained.

Polymer films were elaborated on the basis of soybean protein. By changing denaturing agents and plasticizing systems, such film properties as tensile strength, elongation at break and water resistance can be tuned in quite a wide range depending on the requirements of the materials and the sphere of their application.
