The main scientific direction of department is elaboration of scientific fundamental of synthesis and creating of polyadditional polymers in aquatic and organic media.
The novel linear polymer based materials of multipurpose application with valuable properties were developed as a result of multiannual research in the field of hydrazine-containing polymers.
Basic research of theoretical principles of development of polyurethane ionomers with specified properties have been carried out and the possibility of directional adjustment of their physico-chemical and mechanical properties has been showed. It allows to set the pilot manufacture of aqueous polyurethane dispersions with wide spectrum of characteristics. This novel advanced direction of polymer chemistry allows to solve the problem of environmental protection, to arrange the short-free technologies, by that cinching the high level of technological process safety and improvement of job conditions.
Basic research and elaboration of methods of synthesis of the novel type of polyurethanes with macroheterocyclic fragments in the chain have been first fulfilled. The main principles of such systems' elaborating processes as well as correlation of their properties with structure has been founded. Macroheterocyclic compound based polyurethanes materials (film coverings, water-organic dispersions, polyurethane's foams) possessed a complex-forming ability with metal cations (alkali metals, alkali-earth and heavy metals, including radionuclides).
Hydrazine derivative based polyurethanes are the most promising polymers for medicine purposes due to their specific physico-chemical properties, possibility of the purposeful structure-chemical and phase modification, and, mainly, varying the place of localization and availability of biologically active center.
On account of polymer modification with metal-containing additives or structure-chemical modification polyurethanes become fungicidal in regard to mould fungi (such as Aspergillus niger and other), and steady to biodestruction. Polyurethanes do not decay under the fungus and their metabolites and suppress their growth.
Linear and foam polyurethanes created on the basis of (macro) heterocyclic compounds posses a bactericidal activity with prolonged action (no less than 4 years) against the pathogenic bacteria, which are the most frequently factors of hospital and afteroperating infections: St.aureus, E.coli, Klebsiella pn., Pseud. Aeruginosa, Proteus vulgaris.
With the aim of solution of the problem of utilization of the missile fuel component, heptyl, the novel reactionary hydrazine derivatives on the basis of heptyl were created. They have been used as monomers for polymer synthesis. The method of obtaining of the basic-model polyurethane on the basis of heptyl and it derivatives in organic solution and in the form of aqueous dispersions and foam-forming polyurethanes and based polymer materials of multipurpose application has been elaborated.
Multilayered polymer materials with specific barrier properties for individual protection from toxic and aggressive chemical substances, have been elaborated.
Now the scientific stuff is deal with following fundamental tasks:
As a result of these investigations the new polymer materials with variety of specific properties will be created. Advantages of such materials contain the following: resistance to mechanical stresses, elasticity, hydrofoby, barrier properties, biological activity, and, mainly, polyfunctionality of polymer matrix properties. Listed properties allow to apply these materials in various areas of people activity, parti-cularly in technique, endocrinology, bio-medical purposes, and others.
The objective of investigation is the improvement of preparation properties, employed in chemotherapy of bacterial infections and diseases, which are provoked by micromicetes and yeast funguses especially for activity elevation, life date increasing, toxicity lowering, overcoming the bacteria sustaining against antimicrobial substances, and, mainly, ensuring their goal-oriented transport.
Polymer compositions such as hydrophilic polymer systems, polyurethane(acrylate) hydrogels, foam-forming polyurethanes, polyurethanes lacquers with antibacterial and fungicidal properties will be elaborated on the basis of baseline polyurethane model.
Department can offer the following applied developments of a different level of readiness for implementation in industry:
