The aim of the research is to establish mechanisms of structure formation of hybrid organic-inorganic systems based on urethane oligomers and silicates, depending on reactivity of organic component, to identify the impact of structural organization of OIS obtained on their electrophysical and thermomechanical properties, sorption and sensor activity.The practical significance of the results is the determination of the impact of organic component reactivity on the structure of hybrid organic-inorganic polymer systems with the possibility of obtaining of the materials with predictable special properties. The results can be used as scientific basis for understanding the interconnection of structure, properties and ways of their directional regulation of hybrid organic-inorganic polymer systems. Whereas, the extremely high sensitivity to different types of solvents, which combined with the high selectivity, was revealed for the synthesized systems, the possibility of their practical use as sensor materials exists.
