The only specialized scientific center dealing with the problems of chemistry, physics and technology of polymers, including in the field of nanoscience. Year of establishment – In 1979, the Department of Polymer Chemistry of the Academy of Sciences of the Uzbek SSR was established with the rights of a research institute (Resolution of the Academy of Sciences of the Uzbek SSR No. 27 of February 23, 1979 and the Council of the Ministry of the Uzbek SSR No. 479 of July 11, 1979). In accordance with the Resolution of the CM RU No. 543 of 07.07.81 - transformed into the Institute of Chemistry an
Laboratory of promising polymers synthesis
Under the leadership of academician Rashidova S.Sh. in 1990, the Laboratory of Synthesis of Promising Polymers was created; the laboratory conducts research devoted to the creation of scientific foundations for the synthesis and modification of biologically active natural polymers, the study of the structural features of water-soluble polymers and mixtures using a complex of physicochemical methods.
This makes it possible to obtain data on their molecular structure and supramolecular organization depending on various factors, and also to offer them for medicine, the agro-industrial complex, as well as in pharmacology, biotechnology, etc. (Ph.D. Milusheva R.Yu., Ph.D. Akhymbetova G.D., Ph.D. Avazova O.B., Ph.D. Pirniyazov K.K., Ph.D. Rakhmanova V.N. , рHD Bekchanov I.K., etc.). The laboratory is successfully conducting research in the promising scientific direction of creating polymer formulations of chemical plant protection products, studying the interaction of polymers with living organisms, the mechanisms of the biological effect of polymers on seeds and the regulation of this interaction. creation of a new generation of nanostructured polymer preparations based on natural polysaccharides, their derivatives and application in various sectors of the national economy, based on sources of local polymer plant raw materials.
Scientific developments: 1. A comprehensive waste-free technology has been developed for processing silk production waste to produce chitin, chitosan, and protein. 2. Water-soluble chitosan derivatives have been synthesized: sulfate, ascorbate, citrate and carboxymethyl chitosan. 3. Isolation of chitin and chitosan from a new regional source - cysts of the Aral Sea - has been mastered 4. An environmentally friendly technology has been developed for the pre-sowing preparation of seeds of agricultural crops (cotton, wheat, rice, corn, melons and vegetables) using the encapsulation method using a domestic disinfectant with a stimulating effect - UZKHITAN. 5. A technology has been developed for producing a drug based on protein and chitosan Bombyx mori for fish farming 6. A technology has been developed for the production of the drugs “Askorhit” and “Nanoaskorhit” and their preparative forms, registered with the Agency for Quarantine and Plant Protection.
