Obtaining of immobilized catalysts, new sorbents on base of nitrogen, oxygen and sulphur containing synthetic and natural polymers and research of their sorption and catalytic properties.

New principles for getting immobilized metal polymer complex catalysts and complex forming polymer sorbents were developed. One of the principles is based on use of polymer composition memory and consists of basing active centers of initial polymer on absorbed metal or hydrocarbon substrates and then confirmation as a considerable structure by intermolecule sewing. Other principle consists of construction of immobilized catalytic systems in polymer gels on base of transition metal complexes with oxygen- and nitrogencontaining macroligands, which is connected to resin and swell in organic solvents. Using these principles catalysts were obtained which were immobilized by phosphoril, carboxyl, pyridine, amine and imine functional groups containing new polymer sorbents. Such catalysts behave like homogenous catalysts, because in highly swollen polymers diffusion rate is near to diffusion rate in liquids and can be used again after separating from reaction media like heterogenous catalysts. Such sorbents and catalysts show high activeness, selectiveness and stability in different sorption reactions as well as in oxidation of hydrocarbons, hydrogenation, dimerization, sodimerization and oligomerization reactions. Besides, on base of alkyl-, arylhalogenides aluminium, and titanium,. zirconium compounds new catalysts were obtained for polymerization of vynil monomers.
