The article dwells upon the main economic issues and development of subsurface resource management in the national economy. The question of servitization of subsurface resource management is discussed for the first time. The article focuses on the following issues: the mine rent, the necessity to restructure property in subsurface resource management considering corporate relations; managing the system for economic interests of subsurface resource users, the state, and society; optimizing the payment and taxation systems for use of subsurface resources.

Hyperbranched polyvinyl‐ and polymethylethoxysiloxanes were obtained for the first time by heterofunctional polycondensation of the corresponding organoethoxysilanols derived from relevant monosodium organodiethoxysilanolates. Synthesized structures were characterized using 29Si NMR, 1H NMR and infrared spectroscopies, gel permeation chromatography and elemental analysis. On the basis of the obtained hyperbranched polyorganoethoxysiloxanes, new ‘core–shell’ structured polyvinyl‐ and polymethylsilsesquioxanes with adjustable sizes, different crosslinking densities and variable chemical natures of the core–shell surroundings were prepared, investigated and characterized using 1H NMR and infrared spectroscopies, gel permeation chromatography, thermogravimetric analysis, differential scanning calorimetry and elemental analysis. © 2015 Society of Chemical Industry

PDMS telechelics are important both in industry and in academic research. They are used both in the free state and as part of copolymers and cross-linked materials. At present, the most important, practically used, and well-studied method for the preparation of such PDMS is diorganosiloxane ring-opening polymerization (ROP) in the presence of nucleophilic or electrophilic initiators. In our brief review, we reviewed the current advances in the field of obtaining polydiorganosiloxane telechelics and monofunctional PDMS, as well as well-organized branching centers by the ROP mechanism and catalytic rearrangement, one of the first and most important reactions in the polymer chemistry of silicones, which remains so at the present time.
